本文考虑了气体与其凝结相接触的情况，并根据动力学理论研究了在凝结相表面上发生强烈蒸发或凝结的稳定气体绕流。本文借助于半空间蒸发与凝结问题数值分析的最新结果，系统地导出了描述连续流动极限下气体流动的流体动力学方程组及其在气体与凝结相界面上的边界条件。讨论了动力学边界条件中的凝结因子对流体动力学边界条件的影响。作为该系统的一个应用，研究了两个不同温度的平行冷凝相之间的气体流动。
A gas in contact with its condensed phase is considered, and a steady gas flow around the condensed phase, on the surface of which strong evaporation or condensation is taking place, is investigated on the basis of the kinetic theory. The system of fluid dynamic equation and its boundary condition on the interface of the gas and its condensed phase that describes the gas flow in the continuum flow limit is derived systematically with the aid of the recent results of numerical analysis of the half-space problem of evaporation and condensation. The effect of condensation factor in the kinetic boundary condition on the fluid dynamic boundary condition is also discussed. As an application of the system, the gas flow between two parallel condensed phases with different temperatures is investigated.
