Abstract Trimethyl phosphate (TMP), an organophosphorus compound (OPC), is a promising fire‐retardant candidate for lithium‐ion battery (LIB) electrolytes to mitigate fire spread. This study aims to understand the mechanism of TMP unimolecular thermal decomposition to support the integration of a TMP chemical kinetic model into a LIB electrolyte surrogate model. Reactive intermediates and products of TMP thermal decomposition were experimentally detected using vacuum ultraviolet (VUV) synchrotron radiation and double imaging photoelectron photoion coincidence (i²PEPICO) spectroscopy. Phosphorus‐containing intermediates such as PO, HPO and HPO₂ were identified. Sampling effects could successfully be obviated thanks to photoion imaging, which also showed evidence for isomerization reactions upon wall collisions in the ionization chamber. Quantum chemical calculations performed for the unimolecular decomposition of TMP revealed for the first time that isomerization channels via hydrogen and methyl transfer (barrier heights of 65.9 and 72.6 kcal/mol, respectively) are the lowest‐energy primary steps of TMP decomposition followed by CH₃OH/CH₃/CH₂O or dimethyl ether (DME) production, respectively. We found an analogous DME production channel in the unimolecular decomposition of dimethyl methylphosphonate (DMMP), another important OPC fire‐retardant additive with a similar molecular structure to TMP, which are not included in currently available chemical kinetic models.

We consider a one-dimensional (1D) autoignitive reaction wave in a reactive flow system comprising unburned premixed gas entering from the inlet boundary and burned gas exiting from the outlet boundary. In such a 1D system at given initial temperature, it is generally accepted that steady-state solutions can only exist if the inlet velocity matches either the velocity of deflagration wave, as determined by the burning rate eigenvalue in the subsonic regime, or the velocity of detonation wave as dictated by the Chapman–Jouguet condition in the supersonic regime. Based on our recently published theory that ignition is equivalent to deflagration wave with unity Lewis number, we believe that it is possible to redefine deflagration wave from ignition. Thus, we have developed the general concept of “autoignitive reaction wave” and shown theoretically that there are two distinct regions that can maintain steady-state solutions in both the subsonic and supersonic regimes. Based on this theory, we selected inlet velocities that are predicted to yield either steady-state or flashback solutions and conducted numerical simulations. This novel approach revealed that steady-state solutions are possible not only at the velocity of the deflagration wave in the subsonic regime and the velocity of the detonation wave in the supersonic regime, but also across a broad range of inlet velocities. Furthermore, we identify a highly stable autoignitive reaction wave that emerges when the inlet velocity surpasses the velocity of detonation wave, devoid of the typical shock wave commonly seen in detonation waves. This “supersonic autoignitive reaction wave” lacks the instability-inducing detonation cell structure, suggesting the potential for the development of novel combustor concepts.

<jats:p><div class="section abstract"><div class="htmlview paragraph">To achieve higher thermal efficiency for spark- ignition (SI) engines, advanced rapid combustion technology under high compression ratio is needed. The results of single-cylinder preliminary engine tests using E.U. commercial fuel at 96 RON show that the higher the compression ratio, the faster the combustion speed. Additional engine test and computations using S5R five-component surrogate gasoline with reliable chemistry under various temperature and pressure conditions implied that the autoignition assisted flame played significant role under higher compression ratio conditions, i.e., high temperature and pressure conditions, where apparent increases in laminar flame speeds compared to conventional combustion.</div></div></jats:p>

Abstract The Harrow, Hassidim, Lloyd (HHL) algorithm, known as the pioneering algorithm for solving linear equations in quantum computers, is expected to accelerate solving large-scale linear ordinary differential equations (ODEs). To efficiently combine classical and quantum computers for high-cost chemical problems, non-linear ODEs (e.g., chemical reactions) must be linearized to the highest possible accuracy. However, the linearization approach has not been fully established yet. In this study, Carleman linearization was examined to transform nonlinear first-order ODEs of chemical reactions into linear ODEs. Although this linearization theoretically requires the generation of an infinite matrix, the original nonlinear equations can be reconstructed. For the practical use, the linearized system should be truncated with finite size and the extent of the truncation determines analysis precision. Matrix should be sufficiently large so that the precision is satisfied because quantum computers can treat such huge matrix. Our method was applied to a one-variable nonlinear $$\dot{y}=-{y}^{2}$$ system to investigate the effect of truncation orders and time step sizes on the computational error. Subsequently, two zero-dimensional homogeneous ignition problems for H₂–air and CH₄–air gas mixtures were solved. The results revealed that the proposed method could accurately reproduce reference data. Furthermore, an increase in the truncation order improved accuracy with large time-step sizes. Thus, our approach can provide accurate numerical simulations rapidly for complex combustion systems.

More details Close

The effects of the activation energy on the intrinsic instability of premixed flames were studied by two-dimensional unsteady calculations of reactive flows, based on the compressible Navier-Stokes equation including a one-step irreversible chemical reaction. A sinusoidal disturbance with small amplitude was superimposed on a planar flame to obtain the relation between the growth rate and the wave number, i.e. the dispersion relation, and the burning velocity of a cellular flame generated by intrinsic instability. When the Lewis number was less than unity, the growth rate and burning velocity decreased as the activation energy became lower, because of the decrease of the Zeldovich number. When the Lewis number was unity, the growth rate and burning velocity were almost constant, and they decreased slightly at sufficiently low activation energies. In addition, the dependence of the growth rate and burning velocity on the Lewis number became drastically weaker at sufficiently low activation energies.

A simplified modeling approach is presented for autoignition in a fine micro flowreactor having a gradual temperature increase on the inner surface of the reactor tube wall in the axial direction. Autoignition in the flowreactor is described as a transient, spatially zero-dimensional problem by defining the control volume flowing in the reactor which has convective heat transfer with reactor wall. By this approach, the computational load could be drastically reduced and autoignition temperatures for a stoichiometric methane/air mixture estimated by the proposed model were in qualitative agreement with those obtained by previous experiments. Furthermore, a new normalized sensitivity coefficient for the autoignition temperature in the micro flowreactor was introduced. Sensitivity analysis by this sensitivity coefficient with GRI-mech 3.0 successfully identified essential elementary reactions for autoignition and the cause of the insufficient performance of C1-chemistry for the autoignition process.

Ignition and combustion characteristics of stoichiometric Dimethyl ether (DME)/Air mixture are investigated by using a micro flowreactor with controlled temperature profile which is smoothly increasing from the room temperature to the ignition temperature. Special attention is paid to the multi-stage oxidation in low temperature oxidation. Various flame responses were observed by changing incoming mixture velocity. Stable double weak luminous zones at low velocity region are observed. One-dimensional computation with detail chemistry showed stationary three-stage oxidation defined by the triple peaks in the heat release rate profile at relevant low velocity region. To interpret discrepancy between experimental double weak flames and computational triple flames, gas sampling was conducted for obtaining major species distributions in the flowreactor. The results indicated that low-temperature oxidation occurs in the upstream side of the experimental first luminous zone. Thus, three-stage oxidation can be indi9ated as a stationary phenomon experimentally and computationally.

More details Close

The flame detection characteristics of an electrostatic probe with parallel detection and reference electrodes were investigated on a simple two-dimensional laminar premixed flame. For the large distance between two electrodes, ion current records showed the dependence on the angle of the plane including those two electrodes from the flame surface, that is, the large angle induced double peaks on the ion current record and the decline of maximum peak. On the other hand, for the small distance between two electrodes, in particular less than the thickness of high ion-electron concentration zone, ion current records were independent and constant with respect to the angle. Those features were caused whether both electrodes could be in the flame simultaneously. For the small distance, furthermore, the variation of current peak as functions of passing velocity of the probe through the flale and equivalence ratio was qualitatively same as that for the conventional single electrostatic probe. Consequently, the present probe with small distance between detection and reference electrodes can be applicable to the flame detection.

Numerical calculation was performed to obtain extinction limits of counterflow diffusion flames for blended fuels of CO/H_2 and CO/CH_4,which are produced by thermal decomposition in incinerators. The computer code PRIMIX was converted into a calculation program for counterflow flames, and GRI-Mech ver.2.11 was used as a chemical scheme, eliminating reactions of N and including the radiation heat loss. The stretch rate at extinction of the blended fuel CO/CH_4 has a maximum at a certain mixture ratio as has been shown in the burning velocity. The effects of diluents such as CO_2 and H_2O were also calculated because blended fuels are always diluted by those inert diluents, showing that the stretch rate at extinction has a maximum at a certain dilution rate as well as the mixture ratio of fuels.

A numerical study of low stretched premixed methane-air flame in a counterflow configuration is conducted. The present simulation includes detailed transport properties and chemical kinetics. It is found that near the flammability limit, there is a radiation extinction branch in addition to the normal stretch extinction branch, which has been extensively studied at a large stretch rate. Furthermore, far from the flammability limit, it is found that there are two stable flames, a normal flame and a weak flame which are the results of interaction between the stretch effect and the radiation effect, at a certain extent of stretch rate. In addition, the present results show that the flammability limit obtained in counterflow configuration cannot be extended directly to the flammability limit of its corresponding one-dimensional free propagating premixed flame.

The local reaction zone thicknesses of high intensity turbulent premixed flames, whose Kolmogoroff scale is smaller than a laminar premixed flame thickness have been examined for various mixture ratios by using a microelectrostatic probe with two identical sensors. For a wide range of mixture ratios, the local reaction zone thickness of high intensity turbulent premixed flame is similar to the laminar premixed flame thickness. It is presumed that even in intense turbulence, small scale turbulent eddies may not survive in the local reaction zone. The inner structure of a laminar premixed flame would be preserved at the local reaction zone of turbulent premixed flames.

In order to examine the structure of a high-intensity turbulent premixed flame to a further extent, an attempt has been made to examine the dependence of the characteristics of ion current on the flame configuration, i.e., the local flame curvature. When the curvature is smaller than the critical value, the maximum value of the ion current decreases and the half value period of the ion current increases as the flame curvature decreases. Even though the local flame curvature is constant, the ion current fluctuation changes its shape significantly as the flame path across the probe changes.

What connects ignition and deflagration? -- On explosive transition of deflagration

Youhi Morii, Kaoru Maruta

arXiv:2212.01978　2022/12

More details Close

The general relation between ignition and deflagration analyses was studied theoretically and computationally. Simple analysis showed that the temporal evolutions of normalized fuel mass fraction and the normalized temperature in a 0D homogeneous ignition are equivalent to the spatial evolutions of those in a 1D laminar premixed flame at Lewis number of unity if a spatio-temporal transformation of the flame is applied. Furthermore, computations showed that the degree of reduction in normalized fuel mass fraction in the preheat zone was found to be in the following order: when the Lewis number is less than unity, when the Lewis number is unity (= ignition), and when the Lewis number is greater than unity. This suggested that ignition in the preheat zone near the explosive transition can only occur for 1D laminar premixed flames with Lewis number greater than unity. In summary, the characteristic times of ignition and flame propagation can be of the same order of magnitude in premixed gases compressed by piston in engines or shock waves, and thus the Lewis number determines the existence of premixed flame structure under such conditions.

OH-PLIF measurements and numerical simulations were conducted for co-axial laminar jet flame of CH_4/N_2 in high-temperature air (relevant to High-Temperature Air Combustion Technology: HiCOT) flow and that of CH_4/CO_2 in high-temperature O_2/CO_2 (High-Temperature Oxygen Combustion: HiTOx) flow. In both HiCOT and HiTOx conditions, two types of lifted flames were observed: one (Lifted Flame A) showed strong OH signal near the flame base at high CH_4 mole fraction of the fuel stream (X_<CH4>) and another (Lifted flame B) showed strong OH signal near the flame tip at low X_<CH4>. The present computations successfully reproduced these two types of lifted flames. In the computations, Lifted Flame A was formed near stoichiometric line while Lifted Flame B was formed in the far downstream region of stoichiometric line. Based on the classification using the flame temperature, Lifted Flame A was classified to a tnbranchial lifted flame and Lifted Flame B was classified to mild combustion.

Combustion characteristics of H_2/O_2/N_2 mixture were investigated by using a micro flow reactor with a controlled temperature profile. Two flame responses were observed experimentally by changing the inlet mixture flow velocity. By gas sampling analysis, it was found that reactants were completely consumed in the low flow velocity region in which no flames were visually observed. 2-D computation with detailed chemical mechanisms of gas phase reaction and surface reaction was conducted to examine the effect of radical quenching on the wall surface. By comparing the computation to gas sampling analysis, it was supposed that the surface reaction mechanism may overestimate the effect of radical quenching on the wall surface.

Computational and experimental investigations of radiative counterflow premixed flame at extremely small stretch rate were conducted to clarify the behavior at lower flammability limit. Stretch and radiative extinctions of both Xe-diluted and Kr-diluted counterflow flames were obtained. Flammable region of Xe-diluted counterflow flame was broader than that of Kr-diluted counterflow flame. Lower flammability limit of counterflow planar flame was smaller than that of flame ball using Xe-diluted mixture and larger than that of flame ball using Kr-diluted mixture. These differences of extinction characteristics are due to the lower-Lewis-number of Xe-diluted mixture. Transition from planar flames to a ball-like flame was observed in microgravity experiment and ball-like flame seems to have correlation with flame ball.

Stabilized three-stage oxidation and its pressure dependence of stoichiometric n-heptane/air mixture were examined using a micro flow reactor with a controlled temperature profile. Especially at low velocity condition, three weak flames were observed as spatially separated flames in the different temperature ranges, and these flames correspond to low-temperature reaction and separated high-temperature reactions. As increasing pressure, the first and second flames got stronger whereas the third flame got relatively weakened. Reaction path analysis and sensitivity analysis were conducted to get a better comprehension of such pressure dependence. The results showed that the reaction rate of the third flame depends on that of CO and H_2/O_2 reactions, thus second explosion limit of H_2/O_2 plays a key role in the pressure dependence of the third flame.

The effects of the activation energy on the intrinsic instability of premixed flames were studied by two-dimensional unsteady calculations of reactive flows based on the compressible Navier-Stokes equation. When the Lewis number was lower than unity, the growth rate and burning velocity decreased as the activation energy decreased, because of the decrease of the Zeldovich number. When the Lewis number was unity, the growth rate and burning velocity were almost constant, and they decreased slightly at sufficiently low activation energies. The dependence of the growth rate and burning velocity on the Lewis number became drastically weaker at sufficiently low activation energies.

A study on the visualization of the absorption process in the vicinity of the gas-liquid interface was performed. The system in which CO_2 was absorbed into amine solvents and diffused toward the interior of liquid phase was visualized. The interferogram pattern obtained by phase shifting interferometer showed that the increasing of concentration field instability in liquid phase was observed as time advanced or pressure of the gas phase was increased. This was caused by the density increase of the amine absorbing CO_2 and the liquid was affected by the negative buoyant force which generated natural convection locally. Therefore, pseudo diffusion coefficient in this system was determined larger than that of the molecular diffusion system. It was considered that the self-generated instability enhanced the mass transfer of CO_2 in the vicinity of interface and liquid phase.

O_2/CO_2 combustion technique is suitable for CO_2 capture. A cryogenic air separation using single rectification column was proposed for O_2 production. In the present paper, feasibility study of simplified natural gas combined cycle, NGCC, utilized CO_2 recovery system was deliberated. Power plant consists of three units: ASU (Air Separation Unit), NGCC, and captured-gas compression unit. These units are built on present technologies of conventional plants. Simulation software, HYSYS.Process, was used to simulate and calculate the net thermal efficiency. We have considered two cases; case 1 is 200-300MW output gas turbine, and case 2 is 50MW output gas turbine. As a result, thermal efficiencies achieve 45.4% in case 1 and 43.3% in case 2. In addition, cases have possibilities to increase thermal efficiencies by using of regenerative technique.

CO emission of the gas phase combustion in a packed bed has been investigated experimentally and numerically for lean methane/air premixed mixture. The results show that CO emission is generated at the bed temperature just lower than the temperature in which combustion is completed. This CO emission is due to the early stages of combustion reactions, which does not only depend on the bed temperature but on a residence time of mixture in the bed.

Characteristics of combustion in micro-channel heated by external heat source were examined. We chose quartz channel of inner diameter 2mm, being smaller than the quenching distance of Methane-air mixture. The effects of equivalence ratio and averaged mixture flow velocity on the stability were examined. In addition to the conventional flame, repetition of extinction and auto-ignition which we all "oscillatory combustion" was observed in wide equivalence ratio and smaller mixture velocity conditions. Mechanism of the phenomena was discussed by simple analysis.

For applications of the high-temperature air combustion technology (HiCOT) to waste incinerators, diffusion flames of blended fuel gases and high-temperature air in the stretch flow field were investigated. In this study, extinction limits of the counterflow diffusion flame for CH_4-C_3H_8 blended fuel gases were obtained experimentally and numerically, varying the mixture fraction, fuel concentration, air temperature, and flame stretch rate. Since the flame is unable to stabilize at small stretch rates due to the natural convection caused by buoyancy under normal gravity condition, the experiments were performed under microgravity condition using JAMIC dropshaft in Hokkaido, Japan. Numerical analysis was performed considering detail chemistry and radiative heat loss using the optically thin model. Experimental and numerical results showed that, when the blended fuel is used air temperature is increased, extinction limits are expanded (Figs. A-1 and A-2). As increasing air temperature, however, the extinction limits at low stretch rates are not expanded as much as those at high stretch rates. This reason is presumed as follows : At the high stretch rate region in which the so-called stretch extinction occurs, Damkohler number becomes small and the flame temperature decreases rapidly, so that flame extinguishes; that is, the characteristic chemical reaction time becomes longer than the characteristic flow time. As the air temperature is elevated, the reaction rate increases according to the Arrhenius law. As a result, combustion stabilization is significantly improved and the extinction limit on the high stretch rate side is expanded largely. On the other hand, so-called radiation extinction occurs on the low stretch rate side, owing to a wide flame region with high temperature. The reaction rate increases when the air temperature increases and therefore the extinction limit must be expanded as well. Radiation heat loss, however, also increases in proportion to temperature to the power 4,since the flame temperature becomes higher as the air temperature increases. This is the reason why the extinction limit does not so much expand in low stretch rates as it expands in high stretch rates.[figure]

More details Close

The objectives of this study were to measure ignition times of a n-decane droplet array exposed to a high temperature of 925 K and a low-speed airflow up to 10 cm/s, and to observe the ignition event by high-speed photography of OH emission. The experiments, in which initial droplet size, spacing of droplets and airflow velocity were changed, were conducted in a microgravity field to avoid the disturbance of natural convection. The results showed that ignition time of a single droplet took a minimum at a certain airflow velocity and that the droplet array also had a minimum when the airflow velocity and the spacing between droplets were changed. These phenomena can be explained by the competition between the mass transfer rate and the reaction rate. OH emission at ignition always appeared behind the droplets and the propagated to the forward stagnation point of the droplets.

米国発の大規模数値解析ライブラリと，これと高親和性の研究分担者が開発中の計算高効率化手法とを組合せ，反応性流体の大規模数値計算を実施している．当グループ独自のマイクロ燃焼現象，さらに実用燃焼器を模した小容器内における正ヘプタンの着火・燃焼現象に関する実験（他大学による先実験）を標準現象として，継続可能な共同開発環境の整備を図る計画である．一つ目は，次世代燃焼技術（着火促進）として期待される非平衡プラズマアシスト燃焼の数値解析の実施である．2020年度は，コロナ禍のため当初予定した海外渡航は実施できなかったが，非平衡プラズマアシスト燃焼に関する数値的研究を進め，プラズマ反応から着火～燃焼完了まで，包括的な数値計算を行う手法に道筋をつけ，実際に非平衡プラズマによる着火効果に関する知見を得ることができた．具体的には，換算電界の大小によるその後のプラズマ反応の進行が，単純なエネルギーの大小のみならず，電界付与と局所的な化学種の分布状況に依存することなどが示されている．二つ目は，数値解析ライブラリと計算高効率化手法との組合せによる，他大学で実施された実験（着火～火炎伝播～異常燃焼であるノッキング）との比較による検証である．こちらについても，スパコンで3ヶ月ほどを要した大規模数値計算を完了し，実験結果と圧力履歴および可視化画像からみた現象の全体像とが一致する結果を得ており，現在詳細な結果の分析および考察を進めている．

Reactive fluids, especially combustion phenomena involving complicated chemical reactions, are still known as fields where it is difficult to design equipment based only on numerical predictions. For the purpose of focusing on this situation, we carried out the prediction of combustion phenomenon by numerical analysis for the micro combustion phenomenon unique to this research group. Regarding the fusion of measurement and numerical analysis, it was extremely difficult to track the phenomenon, so we switched to our policy of first improving the accuracy of numerical calculation greatly, and succeeded in numerically reproducing the oscillatory combustion phenomenon with normal heptane during the research period. Although the goal of measurement fusion has not been achieved, the numerical analysis result has been submitted to the world's highest level academic journal in the field of fundamental combustion and accepted. We will continue to try to integrate measurements and computations.

Flame near the wall is largely affected by the chemical boundary condition as well as the thermal and fluidic boundary conditions. The chemical boundary condition depends on the surface reaction, and recently it is proved that it has an important role in the macroscopic combustion field through chemical quenching by radical adsorption and enhancement of gas-phase reaction/autoignition by desorption of the radical from the surface. In the present study, near-wall combustion mechanisms when the surface chemical materials are modified, and thermal and chemical flame-to-wall interaction is investigated in detail. For that purpose, a series of measurements of flame temperature, radical distribution using microscopic laser induced fluorescence, and surface reaction measurement in non-combustion field using electro-discharge-based radical formation as well as numerical simulations with detailed gas-phase and surface reactions are carried out.

It is extensively known that higher hydrocarbon fuels used for automobile and jet engines exhibit cool and hot flames, so-called, multi-stage oxidations. Clarification of multi-stage oxidations are essential for solving knocking and combustion instabilities which limit further improvements of engine efficiencies. In this study, reaction zone of the low-temperature oxidation was successfully separated from multiple weak flames of n-heptane using an original method, "flame chromatography," i.e., a micro flow reactor with a controlled temperature profile (MFR). A separated steady cool flame from multiple weak flames of n-heptane was stabilized for the first time and chemical structure of single cool flame in MFR was clarified by species measurements. Essential information on the capabilities of the current reaction kinetics in predicting low-temperature oxidations and issues of their improvements.

To reduce high computational costs for combustion numerical simulations with detailed reaction models, a new approach “building-up” was taken for constructing a simple reaction model in this study. Several steps of reactions were selected based on combustion phenomenology and model parameters were determined by a semi-empirical method to examine multiple combustion characteristics. The developed simple reaction model was employed in combustion numerical simulations, and satisfactory agreement with computational results obtained by a detailed reaction model and significant reduction of computational time (50 times faster) was confirmed. For further acceleration, the relaxation of stiffness due to strong non-linearity of Arrhenius expressions was tested by Fourier series, which was not completed.

The present flame chromatography enabled desktop-scale experiments for various ignition properties of fuels which were not possible before. The present study applied optical measurements (laser-induced fluorescence) to weak flames where multi-stage oxidation process could be stabilized as spatially separated stable reaction zones. Results showed that Aldehyde and OH radicals were clearly captured in addition to CH chemiluminescence. By combining these images, multistage ignition process in hydrocarbon fuel was reproduced as spatially separated multiple weak flames. It is expected that ignition property index such as Octane number could be introduced from the appearance of the multiple weak flames.

本研究は,温度分布制御マイクロフローリアクタを用いて,燃焼化学反応中におけるイオン反応について調べることを目的とする.将来の代替燃料の一つとして期待され,過去の研究で多段酸化反応を示すことが分かっているジメチルエーテルを燃料に用いた.初めに高温場(約1100K以上)でのイオン反応に注目し,リアクタによって熱炎を分離・定在させ,両火炎位置にインコネル製の電極を設置し,電極間の電位差を計測した.しかし,有意な電位差を見出すことができなかったことから,分離した熱炎反応中におけるイオン反応間では有意な電位差を形成していないと考えられる.次に低温場(約600Kから1100K)でのイオン反応に注目し,リアクタにイオンプローブを設置してイオン電流を計測した.その結果,温度上昇と共にイオン電流が増加した.これにより,従来は計測することが難しかった低温酸化反応の温度域におけるイオン反応について調べることが可能となる.

火炎の最低温度を特定し, その決定因子を明らかにするとの目的に対し, メタンおよび冷炎反応を伴う一般的な燃料の代表としてDMEの双方について調べ, 最低火炎温度の顕現やそのメカニズム解明とともに, 両者の特性の相違について明らかに出来た。通常の燃焼現象では発熱により系の温度が決定し, それに伴い消炎や可燃限界などの現象が現れる。しかし燃焼による発熱反応とは独立に, 外部熱源により温度分布を与えるという, 独自の温度分布制御型マイクロリアクターによって, 通常の熱損失メカニズムによらない消炎現象の特定に成功した。前年までの実験によって見いだされた, メタン空気予混合気による極低速時の低速側限界のメカニズムを数値計算により調べたところ, 低流速に起因する物質拡散により活性種の散逸が起こり消炎していることが分かった。さらに経験的にメタンよりも低温でも反応が維持できるとされ, 冷炎現象が観察されるDMEへ本手法を適用したところ, 多段型の低温酸化反応を定常的に観察できることが明らかとなった。その結果, DMEにおける最低火炎温度, 低温領域における冷炎反応や火炎の振る舞いを把握することができた。数値計算により予測された三段反応と, 実験による二段反応の相違について, ガス分析により詳細な検討を行った結果, 実験では不可視の領域に, 冷炎によるホルムアルデヒドの生成を確認でき, 最終的に数値計算による三段反応と実験結果との一致が確認できた。以上により, 最低火炎温度の概念を詳細に解明できた。すなわち, メタンのように一段の反応が起こる燃料に対し, DMEのように多段酸化反応を示す燃料では, 非常に低温の領域から化学反応が開始していることが実験及び数値計算の双方により確認できた。またこれらの知見をベースに, 既存の化学反応機構の検証を行えることを初めて示した。

Flame pattern formation was examined for the development of microcombustion devices. Premixed methane-air mixture is introduced at the center of two parallel circular quartz plates separated by a millimeter scale distance (<5mm). Two plates are heated with an external heater to create a positive temperature gradient condition along the flow direction. Main result are as follows. 1) In addition to the general perception of a stable premixed flame front at a radial location, a variety of nonstationary flame propagation modes are observed. For lower mixture flow rates and a range of mixture equivalence ratios, a radial flame propagation mode is observed with simultaneous presence of two circular flames at different radial locations. For higher flow rates, a rotating spiral flame propagation mode is observed. In addition to radial and spiral flame propagation modes, random and unsymmetrical flame oscillations are also observed. The rotational rates of the spiral flame fronts were observed to vary from 28 to 83 Hz. A simple analysis is carried out to describe the formation of spiral flames from a steady circular flame. 2) Comprehensive regime diagrams of flame pattern formation in radial microchannels with temperature gradients were drawn based on experimental findings. A premixed methane-air mixture was introduced at the center of microchannels formed by two parallel circular quartz plates that were heated with an external porous burner to create a positive temperature gradient condition in the direction of flow. Combustion behavior in those microchannels at channel widths of 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 mm were experimentally investigated. Regime diagrams of various stable and unstable flame patterns were obtained, confirming that the flame pattern is a strong function of mixture equivalence ratio, inlet mixture velocity, and channel width. Furthermore, some combustion characteristics, such as the rotating frequency of the single pelton-like flame and the triple flame, the radius of the stable circular flame front, and comparison between the major combustion products of the single and double pelton-like flames, were also investigated. After careful examinations, some of the experimental pattern formations were successfully reproduced by computational two-dimensional modeling. Results are submitted to a journal.

本研究では,触媒への電場印加によって,低温域での触媒反応の阻害因子である酸素分子の吸着を防ぎ,より低温域から触媒を活性化する新しい技術を確立することを目標に研究を進めた。酸素分子の吸着が,低温域における触媒反応活性化の阻害因子であるという研究結果と,ガス漏れセンサの原理を逆にした「電場印加」という手法の組み合わせにより,触媒反応の制御を目指した。製作した初期の実験装置によって,電場印加によって触媒反応の活性が変化すること,さらに印可電圧の極性を逆転させることで活性が促進,あるいは抑制される効果が確認できたが,極性の変化に対する触媒温度の上昇傾向が,新しい触媒を使用した場合には一定の傾向を示すものの,複数回実験を繰り返す内に特性が大きく変化したり,極性の促進・抑制の傾向が逆転する場合があることが明らかとなった。こうした結果について検討するため,反応器主要部の構造について,温度の安定などの見地から,反応管内に二枚の白金を電極として設ける形式に変更を行い,上記の再現性と反応促進・抑制傾向の不一致の原因を調べた。赤外線計測による表面状態の把握と,反応管出口の気体濃度計測の二つの方法で触媒反応の進行度合いの把握を図るべ実験を進めた。赤外線計測では計測そのものに電場の影響を排除しきれない懸念が残り,気体濃度計測を優先的に実施した。結果的には,高温による触媒保持部の変形が温度不安定の原因であったことが判明し,反応管内部の触媒保持方法に改良を加えた結果,ライトオフ寸前の触媒温度域で電場印可することで,電場強度に対してほぼ比例的に反応進行度が増大するという信頼できるデータが得られた。

Understanding the combustion characteristics in a microchannel with heat recirculation is important for the development of micro scale combustors. However, small scales prevent the experimental approach. One possible solution for this problem is using of a micro channel under the low pressure conditions. By this, combustion in extremely small tube at normal pressure is expected to be simulated experimentally with meso-scall microchannels. Cylindrical quartz glass tube (i.d.=2.0) heated by flat flame burner which resembles heat recirculation was employed. Effects of pressure (0.06-0.6 atm), flow velocities, and methane-air mixture compositions at extinction limit were investigated. 1. A mild combustion under low pressure was observed both experimentally and numerically. Flame thickness at 0.2atm became ten times larger than that at normal pressure. Therefore, the combustion in extremely small tube which diameter was almost the same as flame thickness was realized. In general, the flame has the curvature near the quenching limit in normal scale tube. However, the present flame retained the flat shape and only became thick. 2. The experimental results showed the upper limits of flow velocity for fuel-lean side is larger than those for rich side, that is, the flammable region didn't become symmetric about stoichiometric ratio. However, the numerical simulation showed the flammable limit was largest near φ=0.8 and furthermore it is expected that upper limits for much leaner mixture become small. 3. Since the quenching Peclet number is very small, heat transfer to the wall is quite large. However, in this research, the flame could be stabilized because of small heat loss by external heating. 4. Close to blow off conditions at lean side, chemical reaction time is faster than that of rich side therefore the flame can be stabilized up to the high flow velocity. This is one interpretation for experimental result of flammable region.

Cathode spots of a vacuum arc are preferably produced on the metallic oxide. They remove the oxide selectively by evaporation and clean the metal surface. In this work investigators have studied the characteristic features of the cathode spots and understand physical background of the unique properties. Main results are summarized below. (1)The analysis of surface using a Kelvin probe reveals that the preferable formation of cathode spots on the metallic oxide results from the lower work function of the oxide compared with pure metal. (2)There exist two different modes of cathode spots produced on the metallic oxide. One has higher energy density than the other. The cathode spots with higher energy density contribute the high rate of oxide removal. The surface treated by high energy cathode spots becomes smoother than that by low energy cathode spots. (3)Two different modes can appear on the same surface at the same time. The ratio of high energy spots to low energy ones depends on the surface condition. The application of NaOH or KOH to the cathode surface of the metal results in the increase of the ratio, which means the increase of the rate oxide removal. The addition of polyethylene glycol also contributes the increase of the removal rate. (4)The hardness of the surface treated by the cathode spots increases because of the rapid solidification of the thin molten layer formed during the removal of oxide. (5)Reduction of gap width between an anode and a cathode results in the increase of the energy efficiency of the oxide removal. The anode potential drop disappears in a gap width shorter than a critical value. In such condition, a major part of the input energy is consumed for the removal of oxide on the cathode.

初年度に燃焼加熱式のヒータへと装置を改良した結果,要求温度などの必要条件を満たしながら振動現象の連続的可視化を可能とすることに成功し,振動燃焼に関してより広範な情報を得ることが出来た。二年度目は,マイクロ燃焼器側における自励振動燃焼の振動周期と振幅に及ぼす流速および当量比の影響を明らかにすること,圧電素子側の要求による振動周期・温度領域との整合をとることから開始した。壁温が1380K,メタンを使用した場合,当量比0.05から1.9の範囲にわたり燃焼可能であり,本研究で想定している振動燃焼は,当量比0.3から1.7の範囲の主として混合気平均流速が30cm/s以下の領域で起こることを明らかにした。このように振動燃焼の発現は広範囲に渡るが,圧電素子を高温に適用する場合,材料のキュリー温度がネックになり,当初予定した燃焼波との直接作用が難しいことが判明した。そのため,ある程度温度の低い領域に圧電素子を設置する必要が生じるが,これにより有効に使用できる温度振動範囲が狭まる問題が出てくることが懸念された。しかしその後,ランガサイトの使用によりキュリー温度の問題を解決でき,本研究の概念を実現可能であることが明らかとなった。圧電素子をマイクロ燃焼器側に適合させるための設計方針が材料の問題で二転したため,予想外に時間を費やしたことが問題点である。結果的には本質的な障壁にはならず,キュリー温度の問題を解決できたが,遅れのために現在圧電素子を導入した段階である。

This research was aimed to develop a new measurement method of velocity, temperature, and concentration in supersonic combustion flow by using a compact diode laser. This method is based on the infrared absorption characteristics of H_2O molecules. A InGaSaP diode laser was selected to detect 1.393 μm band of H_2O vibration-rotation transition. The investigation of the transition lines of H_2O molecules proved that two pairs of transition line are suitable for the temperature measurement in the range of 1300 K - 2000 K and 300 K - 1300 K separately. By collaboration research with a scientist in USA, the diode laser controller, laser corrector optics, and the measurement code were developed, and the assembling of the optical fibers and diode-laser laser optics were conducted. By using a supersonic-combustion test facility of Institute of Fluid Science, Tohoku University, measurement tests of supersonic air-flow and the combustion flow behind a flame holding strut were conducted to confirm the performance of the system developed in this research. For installing the laser probes to the measurement section of the wind tunnel, AR coated optical windows, pin-hole structure, and nitrogen-purge system were employed in order to minimize the effects of the surface reflection, flame radiation, and laser absorption by surrounding air. Results of the measurements showed that, in supersonic air-flow, data of temperature and velocity agreed well with the numerically estimated values without any data compensation. H_2O concentration agreed with estimated value when the background H_2O concentration caused by the residual H_2O via the air reheater of the wind tunnel was reduced. The velocity data for the combustion region was compared with the mean velocity measured by LDV and they agreed well. H_2O concentration was also agreed well with the values estimated based on chemical equilibrium of H_2-air flames in the wake region. From these results, the accuracy and feasibility of the diagnostic method developed in this research were confirmed.

To develop a combustion system that is suitable for CO_2 recovery and has less emission of pollutants, a new combustion method using CO_2/O_2as oxidant has been proposed. However, the epically thin and gray-gas radiation model with Planck mean absorption coefficient, which has no reabsorption, has overestimated the emission, especially for "low-speed" flames. The effects of nongray radiation on the propagation and flammability limit of premixed CH_4/O_2/CO_2 flames were numerically analyzed. The results can be summarized as follows : 1. The nongray radiation effects described by the statistical narrow-band (SNB) model on the laminar burning velocity and flammability limit become larger as the dilution ratio of CO_2 is increased. 2. The gray radiation described by the optically thin model (OTM) loses effectiveness for higher CO_2 dilution ratios and lower equivalence ratios. An experimental and numerical study of diluent (CO_2 or N_2) effects on structure and stability of axisymmetric lifted laminar diffusion CH_4/(Diluent+O_2) flames were also performed over a wide range of the dilution ratio, Z.Results showed that 3. As increasing the Z, attached flames are lifted off at the Z_<lim> (0.72 for CO_2, 0.83 for N_2 diluted flame, respectively) and there were steady responses that the flame length. L_f, shortened and the lift off height, H_f, increased as well as the spreading out of the flame base in the radial direction until the Z_b (0.78 for CO_2, 0.86 for N_2 diluted flame, respectively). 4. The leading edge structure of the lifted flame has a triple flame, where fuel rich premixed wing is smaller than lean one and the trailing nonpremixed flame inclines immediately to the fuel side from trip point. 5. It is also shown that CO_2 effects are stronger than N_2 on the structure and stability due to high heat capacity and low transport rate of Co_2.

Turbulent premixed flames stabilized in a high-pressure atmosphere was studied with the aim of basic elucidation of phenomena of the high-pressure turbulent combustion which has not been explored precisely. The relationship between turbulence characteristics and turbulent flame structure under high pressure was clarified. Investigation of pressure effect for the fractal properties and turbulent burning velocity under high pressure were also made. The laminar flow nozzle-burner is installed in the pressure chamber, and OH-LIF technique were investigated at pressures from the atmospheric pressure up to 3.0 MPa. (0, 0) band and (1, 0) band of the OH radical were excited by an OPO tunable laser and a dye laser pumped by a Nd-YAG laser. The relationship between OH-LIF intensity and pressure was examined. In addition, a simulation considering effects of the broadening of laser line width and absorption spectrum was made and also compared with the experimental result. As the result, it was clarified that the effects of the absorption spectrum broadening was large for the LIF intensity degradation with the increase in pressure. Although the LIF intensity for larger laser line width is smaller than the case of smaller laser line width at atmospheric pressure, the decrease in LIF intensity with pressure is small for larger laser line width. It was proven that to estimate LIF intensity degradation under the high pressure was possible by calculating the overlap integral of laser spectrum profiles and absorption line spectral profiles. From these findings, guideline for the measurement condition of OH-PLIF at high-pressure was established. In continuing, the OH-PLIF method was applied to the instantaneous tomographic imaging of high-pressure turbulent flames. Especially, the fractal analysis of the OH-PLIF image was carried out as the technique which can quantitatively evaluate refinement and complication of the turbulent flame structure. As the result, it was proved that the fractal dimension for high-pressure flame was larger than atmospheric pressure flame even for equal u'/SィイD2LィエD2. The fractal inner cutoff decreased with pressure, but it was proven that the fractal inner cutoff was almost fixed in almost whole range of u'/SィイD2LィエD2 at high pressure. When various characteristic scales such as turbulent scales were compared with the fractal inner cutoff, it was proved that a characteristic instability scale, which corresponds to disturbance scale of maximum growth rate for the hydrodynamic instability, was well correlated to the fractal inner cutoff. These new findings which the hydrodynamic instability has dominant effects at high pressure were also confirmed by the observation of the flame instability with no initial turbulence in flow at high pressure.

Previous studies have shown that the flame stabilized by a strut in supersonic airflow is strengthened by premixing or preburning of fuel hydrogen with air which is injected into combustion zone behind the strut. Especially preburning is expected to improve the flame holding performance significantly because heat and active species produced by the first preburning are supplied to the secondary burning behind the strut. Considering the actual design or the number of engine parts, the feed of air or oxygen with hydrogen into a strut should be troublesome and complicated. Therefore, a direct introduction of air from the main supersonic airflow into the strut is proposed in this study. With respect to this strut with air intake and a preburner inside the strut, flame holding experiments were conducted in supersonic airflow and the following results were obtained. (1) Ignition in the preburner was not difficult and also flame holding was possible in a large extent of hydrogen flow rate by providing an air intake from the leading edge of the strut. (2) Ignition depended on the total temperature of air in the temperature range from 590 to 690 K, but the upper and lower limit of flame holding did not strongly depend on it. (3) Two types of flame holding were observed, namely combustion region did not attach to the rear end of the strut at low hydrogen flow rates and it attached at high hydrogen flow rates. (4) As hydrogen flow rate increased more, temperature in the preburner decreased rapidly, and the flame could not be maintained even in the secondary combustion region.

研究計画書に記載の通り,限界近傍の火炎に対して外部から輻射エネルギーを与え,その挙動を調べた.当量比0.55,火炎伸長率10程度のプロパン・空気対向流予混合火炎に対して集光機構を持たない加熱用ランプで輻射エネルギーを与え,火炎応答を観察したところ,輻射の断続によって燃焼速度の遷移がみられたほか,輻射加熱をステップ状に停止した後に,非定常的な火炎の応答を観察できた. 空気を予熱した場合の対向流拡散火炎について,素反応機構を考慮した数値計算によって火炎帯全域からの輻射量を見積もったところ,予熱空気温度が高温になるほど輻射量が増すことがわかった.これは,高温の空気に向かって化学反応によって生じた輻射化学種が拡散したためである.高温空気使用下で燃料の希薄化が一層進んだ場合には,化学反応による有意な温度ピークが見られず,生成熱が大きく減少したのちも化学反応が維持され,消炎限界が消滅する領域が現れる.この条件下では,輻射化学種の絶対量の減少が著しいため輻射量もさほど大きくないのが特徴である.

This research was aimed to conduct precise observations of the flame structure, to elucidate the relationship between ambient pressure and turbulence scale and intensities, and to explore the effects of ambient pressure on turbulent burning velocities. Turbulent premixed flames for CH_4-air, C_2H_4-air, and C_3H_8-air mixtures were stabilized by a nozzle burner installed in a high-pressure. The following results were obtained. 1) Measured turbulence characteristics showed that turbulence intensities increatsed with increasing mean velocities. Nevertheless, at ordinary pressure, the increase was small in the region of small mean velocities because of an extensive dumping of turbulence. At high-pressures, turbulence intensity linearly increased with the mean velocities in the entire range of the mean velocities. 2) At high-pressures, flame structure becomes fine and complicated. S_T/S_L increased rapidly with increasing u'/S_L particularly for weak turbulence regions (u'/S_L<l), indicating effects the hydrodynamic instability becomes extensive in a high-pressure environment. For CH_4-air flames, S_T/S_L increases with u'/S_L, up to 30 at 3. OMPa for the experimental conditions achieved. 3) The rate of the increase in S_T/S_L for C_3H_8-air flames was smaller than that for C_2H_4-air flames. This is because the flame area increase due to the hydrodynamic instability at high pressures was restrained by diffusive-thermal effects because the larger Lewis number of C_3H_8-air mixtures. 4) The data for awide range of turbulence intensities showed that the u'/S_L dependence of S_T/S_L for C_2H_4-air flames is almost the same as that for CH_4-air flames. Nevertheless, S_T/S_L for C_3H_8-air flame showed smaller S_T/S_L than in the cases of C_2H_4-air and CH_4-air flames. 5) The applicability of existent correlation between S_T/S_L, u'/S_L, aud turbulence Reynolds number, R_L, to high-pressure flames were examined, and it was found that the data of our experiments had a similar tendency to the correlation by Abde1-Gayd but had larger S_T/S_L than their correlation. 1/4 power law of R_L was seen for S_T/S_L in the strong turbulence region (u'/SL>l.0), consistent with the fractal flamelet model of turbulent burning velocity proposed by Gouldin. 6) The best general correlation which can express the experimental data for a whole range of u'/SL and pressure was in the for of S_T/S_L* [ (P/P_O) (u'/S_<1L>) ]^n and the exponent n was close to 0.4.

For the successful development of supersonic propulsion devices the knowledge of ignition and flame stabilization is needed. Since flows within such devices are supersonic, the mixing and reaction times are drastically reduced as compared to the situation within subsonic combustors. A direct implication of the significantly reduced mixing and reaction times is the enhanced sensitivity of the flame stabilization processes in terms of extended ignition delays and the greater propensity of the bulk flame to be extinguished or blown out. This study intends to first, solve the problem of ignition and flame stabilization in low Mach number supersonic airflow by using preburning method. Second, to investigate the combustion mechanism and flame structure of preburned hydrogen in supersonic airflow. Third, to understand the flame stability regime of preburned hydrogen in supersonic airflow. Fourth, to develop a numerical method for computation of supersonic turbulent combustion. Numerical and experimental studies on combustion of preburned hydrogen in supersonic airflow were done. These studies mainly were concerned with ignition, flame stabilization, flame structure and combustion mechanism as well as numerical method for reactive flows. First, the possibility of ignition and flame-holding by preburning method was predicted. It was shown that the temperature limit of auto-ignition is drastically reduced by using the preburning method. In addition, the effect of the preburner equivalence ratio the pressure of the preburner and the supersonic airflow temperature on flame development were studied. It was realized that each of these three parameters had significant effects on flame-holding and combustion development. Futhermore, flame stability limits of preburned hydrogen were predicted by numerical simulation as well as experiment.

年々高負荷化が著しい航空宇宙エンジンにおいて,CO_2フリー燃料としての水素は高速反応の観点からも優れている.本研究は,未来型航空エンジンである,水素を燃料したスクラムジェットエンジンの保炎に関するもので,エンジン内の燃焼領域に衝撃波を入射させることによって保炎性能を向上させることを目的としている. 本年度は,三角柱ストラット保炎器後流の燃焼領域に入射する衝撃波の非対称化,衝撃波入射位置,衝撃波強度,流路閉塞率を変化させ,保炎性能に及ぼす影響を調べた.その結果,以下の知見を得た. 1)衝撃波入射位置がストラット後端に近づくにつれて、再循環流は強化され保炎限界流量は増加することがわかった.逆に,ストラット高さ以上下流へ入射すると保炎限界流量は低下せず、閉塞率の高い場合には逆に上昇する複雑な挙動を示すことがわかった. 2)衝撃波が強いほど再循環流が拡大・強化され、保炎限界流量は増加すること,ストラット後端近傍に入射すると保炎限界流量の増加は大きいが,下流へ入射する場合、衝撃波の強さの違いよる差は少なくなることがわかった. 3)衝撃波非対称入射では,再循環流と噴流は後流内で偏り,保炎限界流量が増加し保炎性能向上に有効であることがわかった. 4)衝撃強度の増大および入射位置の非対称化は,閉塞率を大きくすると,後流幅が減少し保炎限界が低下することが明らかになった.また, 次に,総括反応速度を変化させることを目的として,水素に少量のメタンを添加した場合の保炎実験を行った.その結果,以下の知見を得た. 5)水素流量に対する2%以下のわずかなメタン添加でも保炎限界が大きく狭まり,メタン添加量の増大により,保炎限界全温も上昇することが判明した.これは,メタン分解反応によりHラジカルが消費されるため,メタンの熱分解が完了するまで活性種の増殖が起こらず,着火時間が増大することが原因と考えられる.

Ignition times of a fuel droplet were measured in a high-pressure high-temperature ambient. Suspended n-heptane, n-octane, n-decane, and n-hexadecane droplets with diameters of 0.35 to 1.4mm were quickly immersed in an electric furnace at temperatures up to 950. Attachment of a droplet, movement of the furnace and measurement of ignition were carried out in an air vessel with pressures from atmospheric pressure to over the critical pressure. Relatively long ignition times of small droplets measured under atmospheric pressure could not be observed at high pressures and the diameter below which a droplet does not ignite became smaller with pressure for every fuel used in this research. Ignition time decreased monotonously with pressure, and even at supercritical pressures, the ignition time behavior did not change much. Being different from the case of combustion, it is suggested that drastic change of properties did not take place in ignition processes. This is basically because the surface temperature of the droplet is much lower for droplet ignition phenomena in comparison with the droplet burning. At the second stage of the research, flame spread phenomena in a suspended fuel droplet array were investigated for n-decane and n-hexadecane in a high-pressure ambience. Seven droplets of the same size were arranged horizontally at equal spacings. Flame spread rates were measured based on OH emission histories detected by a high-speed video camera with an image intensifier for droplet diameters of 0.50,0.75, and 1.0mm at ambient pressure from 0.1 to 2.0MPa. Results showed that, as droplet spacing became smaller, flame spread rate increased and had a maximum value at a certain spacing. A further decrease in droplet spacing caused the spread rate to decrease due to the large latent heat of vaporization. Flame spread rate decreased with pressure and no flame spread was observed at the pressure over the critical pressure. This is due to the rapid decrease in flame diameter with pressure.

マッハ数2.5、全温550-800Kの超音速空気流に、長さ80mm高さ20mmの二次元楔状ストラットを置き、ストラット背後から水素燃料を噴射した。ストラット後流に衝撃波を入射させると、後流全体に燃焼領域が安定に確保できる。昨年度に引続き、この保炎性能を詳細に調べ、数値シミュレーション結果との比較など進めた。昨年度はLDV計測による流速分布について調べたが、今年度は、ストラット後流の保炎領域について、濃度分布と温度分布、さらにはLIF計測によるOH発光など明らかにした。水素燃料の増大と共に、後流において、再循環流と水素噴流が衝突してできる対向流型の火炎が削減して、超音速流と亜音速再循環流の間のせん断層内の主な燃焼領域が移動するが、濃度分布と温度分布はこれらの現象を立証するデータとなった。また、短時間のOH分布計測は、上記の現象を更に明確にすると共に、再循環流内の化学的に非平衡状態にあるため、ときには全く凍結状態でOHが存在しなかったりお、ときには反応が急速に進行して、OHが十分に存在していることがわかった。流れが必ずしも定常でないため、両方の性状が交互に出てくると考えられる。更にこの保炎メカニズムを確認することと、保炎性能を高めることを目的として、水素燃料に空気を予混合して噴射し、混合を結果として速める実験を行った。予混合化は、むしろ保炎性能を悪くする結果になった。これは、空気の混入によって、噴射の運動量を増大させ、先述のように、火炎を下流に押しやる方向に移動させることになるからである。更に予混合化を進めると、リセス内で一次燃焼することになり、全く異なった保炎形態へ移行する。これらについて詳細に検討を行った。

本研究では、無重力環境を利用することによって、可燃限界を計測する際の大きな障害の一つであった自然対流の影響を排除でき、同時に極低速強制対流が温度勾配である場でも実現可能であることに初めて着目した。すなわち、極低速の対向流を用いて無重力場実験を行う本方法により、流体力学的な要因や燃焼器等への熱損失に依存しない、純粋に化学反応のみによって決定される、混合気に固有の可燃限界の計測が初めて可能となると考えた。無重力場で対向流バ-ナを使用し、かつ混合気の濃度の制御を行った例はまだ無い。そこで小型のコンピュータおよびDA変換器、マスフローコントローラを使用した精密な混合気制御系を含む無重力場実験装置を新たに製作して、予混合双子火炎の可燃限界の計測を行った。その結果、従来、通常重力場で計測されていた可燃限界よりも、無重力場ではさらに希薄な混合気も燃焼可能であること、また一般的に良く知られている火炎伸張による消炎限界の他に、極低速域において輻射熱損失によって引き起こされる輻射消炎限界が存在することを初めて確認できた。また、混合気のルイス数によって、輻射消炎時の火炎が特異な挙動を示すことが明らかとなった。したがって、従来からの可燃限界の概念を整理し、統一的に解釈するためには、理論解析、数値計算によるこれらの現象の理解・解明を図ると同時に、さらなる無重力場実験が必要になるものと思われる。

最も反応速度の高い水素燃料は、燃焼速度のみならず、発熱量、断熱火炎温度、定圧比熱、拡散係数、熱伝導率のいずれをとっても大きく、また可燃限界が広く、着火エネルギーも小さい。それにもかかわらず、燃焼領域の安定化は困難であり、種々の特殊な技術を加味しないと、与えられた空気条件に必ずしも安定な火炎が得られるとは限らない。そこで、楔状保炎器の背後に広がる燃焼領域に衝撃波を導入し、その保炎に対する効果を調べるとともに、保炎メカニズムを明らかにすることを目的とした。実験的には、マッハ2.5の全温550-800Kの乾燥した空気流に長さ80mm高さ20mmの二次元楔を置き、衝撃波発生板によって衝撃波を入射した。観察領域の両面をガラスにして光学的観察を行えるように工夫された。発生板の位置や水素燃料の量を変えて燃焼領域の安定範囲を調べ、衝撃波入射位置を後方に移動すると燃焼安定性は悪くなり吹き飛びやすくなることなどわかった。その安定性は、保炎器の背後に再循環領域が大きく発達し、衝撃波入射位置が後方に移動すると、この再循環が急速に弱まることがLDV計測によって解明された。数値計算も同時に行い、再循環領域の動きが確認されると同時に反応率の分布が求められ、水素燃料の量に応じてどのように変動するか明らかにされた。すなわち、保炎器背後からの水素噴流の速度が大きくなると、再循環流の高温空気と衝突してできていた反応帯が消滅して、主流超音速と亜音速領域のせん断層に反応帯先端が移動して種々の条件に対して極めて敏感な燃焼安定性に変わる。また、観察領域内では超音速主流に反応帯ができないことなど分かった。
