Abstract

Correct studies of relaxation phenomena in rarefied gas flow near a solid surface require precise modeling of the collisional energy and the momentum exchange between gas particles themselves and the surface. In this work, some structural stochastic models for such collisional processes (including chemical reactions case) in rarefied gas media near the surface are proposed. Some results of numerical calculations are submitted.
