Numerical Study of Essentially Unsteady Evaporation

Abstract

We study numerically, essentially unsteady evaporation and heat transfer of a rarefied gas using the S-model kinetic equation. Three particular cases are considered: one-dimensional flow from a flat surface and purely radial flows from the surface of a cylinder or a sphere. We present numerical results for different values of the evaporation coefficient and saturated vapor density which demonstrate the strong dependence of the flow on these two parameters.
