    Abstract In this study, a clear-air turbulence event was reproduced using a high-resolution (250 m) large-eddy simulation in the Weather Research and Forecasting (WRF) Model, and the resulting wind field was used in a flight simulation to estimate the vertical acceleration changes experienced by an aircraft. Conditions were simulated for 16 December 2014 when many intense turbulence encounters (and one accident) associated with an extratropical cyclone were reported over the Tokyo area. Based on observations and the WRF simulation, the turbulence was attributed to shear-layer instability near the jet stream axis. Simulation results confirmed the existence of the instability, which led to horizontal vortices with an amplitude of vertical velocity from +20 to −12 m s−1. The maximum eddy dissipation rate was estimated to be over 0.7, which suggested that the model reproduced turbulence conditions likely to cause strong shaking in large-size aircraft. A flight simulator based on aircraft equations of motion estimated vertical acceleration changes of +1.57 to +0.08 G on a Boeing 777-class aircraft. Although the simulated amplitudes of the vertical acceleration changes were smaller than those reported in the accident (+1.8 to −0.88 G), the model successfully reproduced aircraft motion using a combination of atmospheric and flight simulations.

    We have conducted large-eddy simulations of laminar separation control by the DBD plasma actuator over NACA0015 airfoil. The control effects are investigated for the case of the single plasma actuator and the case of the multiple plasma actuator. Reynolds number based on the chord length is 63,000 and the angle of attack is 16 degs. For the case of the single plasma actuator, the reattached flow separates again near the trailing edge. On the other hand, separation control by the multiple plasma actuator can suppress the re-separation near the trailing edge. This suppression leads to improvement of the lift coefficient compared to the case of single plasma actuator.

    Aerodynamics of horizontal axis wind turbine blades of a simple experimental model with an active flow control using a DBD plasma actuator has been studied by large-eddy simulations based on a high-order accurate and resolution computational method. Large-scale parallel computations have been conducted using message passing interfaces and 18,800 cores of the K computer. Results correspond to first revolution after the DBD plasma actuator starts have been presented. The impacts of the DBD plasma actuator on flow fields around the blades have been shown. Up to a 20% increase in revolution-averaged torque generation has been attained. Moreover, this improvement of torque generation due to the DBD plasma actuator has been similar to those reported in the experiment.

    We have conducted large-eddy simulations of the turbulent separation control by the DBD plasma actuator over NACA0015 airfoil. Reynolds number based on the chord length is 1,600,000 and the angle of attack is 20.1 degs. The location and operating conditions of the plasma actuator are changed as the numerical parameter. It is clarified that the effective mechanism for the turbulent-separation control by the burst mode is to induce the pairing of the large-scale vortex shed from the turbulent-separation shear-layer. The large-scale vortex results in the not only the momentum induction from freestream to the boundary layer but also the lift improvement through its convection. In addition to this control mechanism, various control effects can be achieved depending on the settings of the DBD plasma actuator.

    This paper studied control of separated flow over an NACA0015 airfoil by a single dielectric barrier discharge (DBD) plasma actuator installed at the leading edge using large-eddy simulations with high-order accurate and high-resolution numerical scheme. A chord-based Reynolds number of 260,000 and an angle of attack of 18.8 degrees were considered. A phenomenological DBD plasma-actuator model was employed to provide the spatial body force distribution. The unsteady operation so-called a burst mode actuation was introduced and two burst frequencies of 1 and 6 with constant burst ratio of 0.1 were analyzed. Effects of the burst frequency on flow control performance were discussed in detail. Results showed DBD plasma actuator with burst frequency of 6 provided better control authority in comparison with the burst frequency of 1.

    Large-eddy simulations of a separated flow over NACA0006, NACA0012 and NACA0015 airfoils, which are controlled by a DBD plasma actuator, are conducted to investigate the effect of an airfoil configuration on separation control. Reynolds number is 63,000 for all cases. In these simulations, the position and operation conditions of a DBD plasma actuator are varied as the simulation parameters. The most effective position for separation suppression is near the separation point for all airfoils. The burst frequency with 6 is more effective than 1 to increase the lift-drag ratio in present conditions. The effect of separation control becomes smaller for the cases with larger reverse flow region, and the development of this region significantly influence on the control. Strouhal number based on the momentum thickness is almost the same value in each airfoil case. These values of the burst frequency 6 cases are similar to effective Strouhal number suggested in the past study.

    Present paper investigated control of separated flow over an NACA0015 airfoil by a single dielectric barrier discharge(DBD) plasma actuator installed at the leading edge using large-eddy simulations with high-order accurate and high-resolution numerical scheme. A chord-based Reynolds number of 260,000 and an angle of attack of 18.8 degrees were considered. A phenomenological DBD plasma actuator model was employed to provide the spatial body force distribution. The unsteady operation so-called a burst mode actuation was introduced and two burst frequencies of 1 and 6 with constant burst ratio of 0. 1 were analyzed. Results showed that the DBD plasma actuator could change dynamic behavior of shear layer separated from the leading edge and lead to reattachment near the leading edge when the actuation with burst frequency of 6. However, it was not able to lead to fully attached flow on the upper surface of the wing due to the adverse pressure gradient. Lastly improvement of time-averaged aerodynamic performance attained by flow control was also discussed.

It is clarified that the control effects are different from each airfoil even if same numerical parameters are used. Effective position of actuator is near separation point to suppress the separation for all airfoils. The effects of separation control become smaller for cases with larger separation regions, and the separation development significantly influence on the control.

    I attempted to theoretically elucidate the multi-scale interaction of the flow by performing a global stability analysis of the fluid for a non-stationary and non-uniform flow field. Focusing on the energy transient amplification in the non-orthogonal mode, we succeeded in acquiring some new findings on the drag reduction of the spanwise wall oscillation and the transition delay of the boundary layer. In the spanwise wall oscillation, oblique streaks grow and the original streak weakens, which is consistent with the result of maximum transient amplification of energy. And, it was confirmed that a small oblique flow structure existed near the wall in the boundary layer, which also coincided with the maximum transient amplification mode of energy. In addition, new discoveries and proposals were made regarding the transition of the three-dimensional boundary layer of the aircraft swept wing and the transition delay effect of micro distributed roughness.

    This research is targeting flow field in an oscillating channel or around a two-dimensional hill. That is non-equilibrium turbulent under acceleration and deceleration of the mainstream, in which turbulence production and dissipation are not balanced. We studied a mechanism to explain and control turbulence coherent structure such as low speed streak and streamwise vortex generated near the wall surface. In particular, we developed a program code to compute transient growth of non-modal stability of the flow, and analyzed the stability on the base flow that changed in spatiotemporal. Turbulence structure by direct numerical simulation was compared with that by the linear analysis and we obtained useful knowledge for constructing a smart flow control strategy.

    省エネルギーや環境負荷低減の観点から,摩擦抵抗低減,伝熱促進,騒音低減等を目指した,乱流の高効率で自在な制御技術の要請が高まっている.工学上対象となる流れの多くは,壁面に沿う勇断乱流であり,優れた制御を達成するためには,壁面近傍の縦渦構造に適切な作用を施すことが有効であることが,近年の研究で明らかにされている.一方,様々な乱流制御手法の中で,壁面のスパン方向の周期振動が,顕著な抵抗低減効果を達成することが知られている.比較的単純な制御則であるものの,抵抗低減機構には未解明な部分が多く,最適化,実用化に向けて,更に詳細な解析が必要である. 本研究では二年間に,チャネル乱流の直接数値計算とエネルギー過渡安定性解析の二つの手法を用いた解析を行った,平成22年度は主に直接数値計算からの縦渦構造の条件付き抽出から,壁近傍でレイノルズ応力を生成する主な原因となっている縦渦運動の変化を詳細に示し,摩擦抵抗低減を引き起こす運動と関連づけて説明をおこなった. 平成23年度は平行平板間流れのエネルギー過渡成長におよぼすストークス層効果の検証を行った,従来研究で指摘されている通り,平行平板間流れで最も増幅するエネルギーの過渡成長モードが,直接数値計算で確認される壁近傍の低速ストリークのスケールと一致することを確認した.次にスパン方向の壁振動制御時に見られるストークス層が重畳する場合についての解析を行い,低速ストリークのスケールと一致するモードの過渡成長率が変化することを初めて確認した.これらの結果より,直接数値計算で見られるスパン方向壁振動時の摩擦抵抗低減と,低速ストリークに対応するモードの過渡成長率の低減の間の関係性が示唆された.以上,本研究ではスパン方向の壁振動によって,壁面せん断流の過渡安定性や乱流構造の変化に焦点を当て,乱流制御手法の最適化,実用化にむけて有用な知見を得た.
