Multiscale study on molecular transport process near nonequilibrium vapor-liquid interfaces governed by three physical laws

本研究旨在用多尺度方法研究非平衡态下气液界面的分子输运过程。结果可概括为：（1）利用激波管和分子气体动力学确定蒸发和冷凝系数，（2）利用声波确定蒸发系数，（3）弯曲气液界面动力学边界条件的制定，（4）利用分子气体动力学对任意形状气液界面非稳态动力学边界条件的渐进分析。

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.
