Abstract

Stochastic modeling of collisional physicochemical processes in rarefied gas and plasma media has yielded a mathematical model which makes it possible to numerically investigate, on the molecular level, the nonequilibrium kinetics of the translational and internal degrees of freedom of particles. The proposed algorithm is validated by solving a problem concerning relaxation of a temperature inhomogeneity in a uniformly expanding gas and comparing the results with experimental data and other solutions. The stochastic model can be used to solve various engineering problems in aerodynamics.
