| Research Abstract |
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.
