Abstract : Analytical and experimental studies of the axially symmetric turbulent mixing of a hot, partially-ionized subsonic argon jet with an annular subsonic cool helium stream are presented. A model for the flow is developed, and the resulting integro-differential equations are solved numerically on a high-speed electronic digital computer. Experimental results obtained from physical measurements at one-atmosphere pressure within the high-temperature arcgenerated plasma are used to evaluate the analysis. Good agreement between analysis and experiment was observed. The various analytical approaches are reviewed briefly. In particular, a discussion of the merits of the various expressions for the turbulent shear stress is presented in terms of their application to the problem in question. Equations of continuity, helium diffusion, momentum, energy, and state for the multicomponent, partly-ionized, axially symmetric, subsonic, field-free, turbulent plasma flow are derived. (Author)
