    Stator coils of automobiles in operation generate heat and are cooled by coolant poured from above. The flow characteristic of the coolant depends on the coil structure, flow condition, solid–fluid interaction, and fluid property, which has not been clarified due to its complexities. Since straight coils are aligned and layered with an angle at the coolant-touchdown region, the coil structure is simplified to a horizontal square rod array referring to an actual coil size. To obtain the flow and wetting characteristics, two-phase fluid flow simulations are conducted by using the phase-field lattice Boltzmann method. First, the flow onto the single-layered rod array is discussed. The wetting area is affected both by the rod gap and the wettability, which is normalized by the gap and the averaged boundary layer thickness. Then, the flow onto the multi-layered rod arrays is investigated with different rod gaps. The top layer wetting becomes longitudinal due to the reduction of the flow advection by the second layer. The wetting area jumps up at the second layer and increases proportionally to the below layers. These become remarkable at the narrow rod gap case, and finally, the dimensionless wetting area is discussed at each layer.

    Imbibition of single droplet onto porous surface can be observed in engineering devices such as the oil mist filter, inkjet printings, etc. This two-phase flow is governed by physical properties of liquid and porous media. When the droplet size is comparable to the pore scale, the droplet behavior additionally depends on the structural characteristics of the porous media, which has not been clarified yet. It requires to consider not only the physical properties of two-phase flow but also the solid structure. We employed the phase-field lattice Boltzmann method (PFLBM) to compute the two-phase flow on the complicated structures. Since the conventional PFLBM has less precision in the solid representation, wettability and the phase volume consideration on curved boundaries, we improved this method by employing hybrid interpolated bounce-back scheme in the three dimensional system with considering wall normal direction geometrically. It shows the reasonable droplet behavior on a flat plate inclined from the grid line. A static droplet on a sphere is represented by the reasonable position and shape of the contact line. The phase-volume error derived from the conventional interpolated bounce-back is successfully suppressed. Next, the characteristic of the droplet entrapment and/or infiltration by isotropic open cell (Kelvin cell) porous media is numerically studied. It is found that the threshold wettability exists between entrapment and infiltration regardless of the surface topology of the porous media. As the droplet size becomes smaller, the effect of the porous surface becomes remarkable in the threshold contact angle and infiltration ratio at higher contact angle. In case of the droplet entrapment above the porous surface, the lyophobicity of the porous surface becomes remarkable, which merges to the given contact angle at the super-lyophobicity due to the less wetted ligaments.

    本研究の目的は，1)固気液三相の温度場，気相中の溶媒濃度場，液相中の溶質濃度場，および液相の蒸発の全てを同時に解析可能な，汎用的気液混相流解析ツールの開発，2)開発した手法を用いた複雑構造周りにおける液滴蒸発後に形成される三次元溶質膜形状の制御因子の解明の二点である．2022年度には目的1)のうち，界面の大変形を伴い，かつ気液間の熱容量比が大きい気液二相流現象を取り扱うことが可能な，気液二相熱流動シミュレーション手法の開発を行った．本研究では，複雑構造周りにおける界面の大変形の計算に適した二相系格子ボルツマン法をベースとして手法開発を行った．開発した手法の計算精度を検証するために，周囲の気体と等速で運動する液滴のシミュレーションを行った．このとき，気液の密度比が大きい場合には，界面周りの速度場に大きな誤差が生じ，加えて熱容量比が大きい場合には，液滴周りで非物理的な温度分布を示すことがわかった．この問題は計算スキームがガリレイ不変性を満足していないことに起因すると考え，高次精度でガリレイ不変性を満足するキュムラント格子ボルツマン法を実装することで，問題の解決を図った．これにより，液滴周りの非物理的な温度分布の発生を抑制することができた．また，表面張力を考慮した計算では，表面張力の計算誤差に起因して，気液界面周りの速度誤差も大きくなった．そこで，従来手法において用いられる複数の表面張力モデルについて，計算精度の評価を行い，生じる速度誤差の小さい表面張力モデルならびに差分スキームの提案を行った．

    本研究では複雑流路内の気液二相流解析に適した手法である二相系格子ボルツマン法に対して，蒸発の影響を実装した．蒸発現象を解析可能な二相系格子ボルツマン法を開発した例は過去に報告されているが，従来手法では液相の蒸発速度を過剰に見積もる問題が報告されていた．本研究では，この問題の原因が格子ボルツマン法の時間発展方程式に含まれる誤差項にあると考え，誤差項を打ち消すための項を付加することでこの問題を解決した．加えて，相の移流拡散方程式として二階の偏微分方程式である保存形Allen-Cahn方程式を用いることで，従来手法で用いられるCahn-Hilliard方程式（四階偏微分方程式）を解くよりも低コストかつ安定的に高密度比解析が可能となった．また，本手法を平板上三次元蒸発液滴に適用し，親液性表面において液滴の接触線付近の蒸発速度が高くなる現象を再現することができた．以上の結果をPhysical Review Eに発表した． 次に，温度場の影響を実装した二相系格子ボルツマン法の開発に着手した．しかしながら気液界面が変形・移動する解析において，界面付近で非物理的な温度分布が現れることがわかった．そこで本研究では温度分布を考慮した二相流解析の足掛かりとして，液相粘度の異なる複数の等温場解析を行うことで，温度場が液の濡れ広がりに及ぼす影響を疑似的に調査した．解析対象として水平角柱群への液の流下現象を選択し，液相粘度と角柱間隔が角柱表面の濡れ面積に及ぼす影響について調査した．その結果，レイノルズ数の平方根と角柱間隔の積を用いて濡れ面積を整理することで，統一的な傾向を見出すことができた．単層の角柱群の結果を混相流シンポジウムにて発表し，混相流学会誌「混相流」の精選論文特集号に選ばれた．また複層の角柱群の結果をICCHMTにて発表し，EntropyのSelected paperとして発表した．
