| Research Abstract |
This research project has been performed to clarify molecular transport process at vapor-liquid interfaces in nonequilibrium states by multiscale methods. The results can be summarized as follows :(1) Determination of evaporation and condensation coefficients by shock tube and molecular gas dynamics,(2) Determination of evaporation coefficient by sound wave,(3) Formulation of kinetic boundary condition at curved vapor-liquid interface, and (4) Asymptotic analysis of unsteady kinetic boundary condition at arbitrarily-shaped vapor-liquid interface by molecular gas dynamics.
