| Outline of Final Research Achievements |
The aim of this study is to determine the kinetic boundary condition for the Boltzmann equation at a vapor-liquid interface during net evaporation or condensation. By using the constructed kinetic boundary conditions in the present study, we simulate vapor-liquid two-phase flows with net evaporation or condensation, e.g., cavitation bubble collapse with phase change. From this results, we shows that the kinetic boundary conditions at vapor-liquid interfaces during net evaporation and condensation are the functions of liquid temperature based on the numerical analysis of the Enskog-Vlasov equation (Enskog-DSMC method). Furthermore, we propose the boundary condition for the fluid-dynamic-type equations at a vapor-liquid interface during net evaporation and condensation.
