Linear kinetic analysis of evaporation and condensation

Abstract

The mixing model was used for analysis of linear kinetic problems of phase transition. The asymmetry of evaporation and condensation, which occurs for intensive processes, remains even for the case of linear approximation. The analytical solution for kinetic jumps of pressure and temperature at the condensed phase surface was obtained: it complies with the results of the classical linear theory. The key result of this study is analytical solution for dependency of pressure jump (condensation) on the temperature factor. This dependence has a minimum near the margin between the abnormal and normal regimes of condensation.
