Asymptotics of the near-equilibrium relaxation of the charge composition of a steadily expanding plasma
Abstract
The asymptotics of the near-equilibrium relaxation of the plasma charge composition is examined in terms of the corresponding Damkohler number using quasi-one-dimensional stationary flow of a doubly ionized beryllium plasma in a Laval nozzle. A method is proposed for the numerical modeling of this class of plasma flows. For conical Laval nozzles, a numerical experiment has been carried out which models smooth flows and flows with a shock wave. The need for modifying the traditional representation of the Damkohler number in terms of the characteristic gasdynamic time is demonstrated.
