摘要

分析了求解蒸发问题的特点。研究了连续介质力学方程边界条件设置的不同方法。本文介绍了用连续介质力学方程和动力学玻尔兹曼方程，以及分子动力学模拟方法求得界面附近分子的速度分布函数的结果。确定了分子远离界面的分布函数。结果表明，所考虑的问题的蒸发系数和凝结系数接近统一。

Boundary Conditions for Transport Problems on the Evaporation Surface

The peculiarities of solving evaporation problems are analyzed. Different methods of setting boundary conditions for continuum mechanics equations are studied. This paper presents results of applying continuum mechanics equations together with the kinetic Boltzmann equation, as well as using molecular dynamic simulation, to find the velocity distribution function of molecules near the interface. The distribution function of molecules moving away from the interface is determined. It is shown that the evaporation and condensation coefficients in the considered problems are close to unity.
