Constructions of kinetic boundary condition at vapor-liquidinterfaces and its application to fluid dynamics

在本研究中，基于Enskog-Vlasov方程确定了汽液非平衡态的动力学边界条件。本研究的目的是构建KBC，并将KBC的知识应用于流体动力学分析。模拟结果表明，在较低的液体温度下，我们模拟得到的KBC的速度分布为各向异性的高斯分布，这一结果与以前的分子动力学模拟结果定量地一致。而且，液体温度变得稍大，各向异性高斯的幅度变大。

In the present study, the kinetic boundary condition (KBC) at vapor-liquid nonequilibrium states was confirmed based on the Enskog-Vlasov Equation. The aim of this study is to construct the KBC and to apply the knowledge of the KBC for the fluid dynamics analysis. The simulation results showed that at a low liquid temperature, the velocity distribution of the KBC obtained by our simulation is anisotropic Gaussian; this result agrees quantitatively with the results of the previous MD simulation. Also, the liquid temperature becomes slightly larger, the magnitude of the anisotropic Gaussian becomes larger.
