Abstract

The Boltzmann kinetic equation, the equations of continuum mechanics, and the system of moment equations for homogeneous nucleation are applied to investigate the vapor flow that occurs near a phase interface during its evaporation from a flat surface due to an instantaneous increase of the surface temperature. It is shown that the flow formed as a result of evaporation has a specific structure consisting of several zones. The influence of the bulk vapor condensation on this structure is examined.

非定常蒸发过程中成核过程对流动结构的影响

本文应用玻尔兹曼动力学方程、连续介质力学方程和均匀成核的矩系方程，研究了由于表面温度瞬间升高，蒸汽从平面蒸发时在相界面附近发生的流动。结果表明，由于蒸发而形成的流动具有由若干区域组成的特定结构。研究了体积蒸汽凝结对该结构的影响。
