Analysis of the relaxation of a nonequilibrium gas or plasma in a nozzle

  • Published:
Soviet Physics Journal Aims and scope

Abstract

An economical and consistent, in mathematical respects, method of analyzing the flow of a relaxing gas or plasma in a supersonic nozzle is developed. The method is used in analyzing the vibrational relaxation of a two-phase mixture in the nozzle of a combustion gasdynamic laser. It is shown that the use of the Gear method in the numerical integration stage permits passage of the near-equilibrium sections with a large spacing, which substantially cuts down the computing time.
