This research focuses on numerical simulation of mixing of plasma chemical species in the discharge and near-outlet regions of the worldwide unique type of thermal plasma generator with hybrid stabilization of an electric arc by axial argon flow and tangential water vortex. The results show the effect of mixing of plasma species on the arc performance for currents 150-400 A. Calculated radial temperature and velocity profiles exhibit very good qualitative and quantitative agreements with measurements.
