| Outline of Final Research Achievements |
The aim of this study is to examine a kinetic boundary condition that depends on liquid temperature for the Boltzmann equation in a vapor-liquid two-phase system during unsteady net evaporation/condensation in a strong non-equilibrium status.We carried out numerical simulations of the unsteady heat and mass transfer in the vicinity of interface at the strong non-equilibrium status by using EV-DSMC method; then, we constructed the kinetic boundary condition that can prescribe the heat and mass transfer in the vicinity of the interface in the frame work of the macroscopic fluid mechanics. We proposed a novel model of the bubble dynamics with phase change taken into consideration. We also investigated the bubble dynamics with phase change.
