A theoretical investigation is presented of the flow of a radiating ionized gas through a supersonic expansion nozzle. The gas model employed is that of singly ionizable argon possessing a nonequilibrium concentration level and a nonequilibrium energy distribution. A consistent mathematical description is devised which includes the effects of a multistep collisional ionization process as well as those of bound-bound and bound-free radiative transitions. Emphasis is placed on the contributions of the nonequilibrium radiation field in the general case as well as the optically thick and thin limits. An explicit form of the critical speed of a two temperature gas is also presented. Author
