Abstract

A numerical simulation of nonequilibrium physico-kinetic processes in a rarefied, chemically active plasma is presented. In the simulation, discrete solutions are obtained for the nonlinear Boltzmann equations governing the processes of photoionization, binary ion-molecule reactions, and superelastic recombinational Coulomb collisions. The theoretical principle of the simulation is discussed, and the computational scheme is described in detail. In order to illustrate the applications of the simulation, the nonequilibrium hydrogen distribution functions of a three component system of electrons, ions, and hydrogen atoms were calculated, and the results are given in a series of tables.
