This paper describes numerical results of a thermal and chemical nonequilibrium plume of high-temperature air. The gas is expanded from an orifice into low-density stationary air as a free jet. The gas considered here is high-temperature air composed of N_2, O_2, N, O, NO, NO^+and e^-, and translational-rotational and vibrational-electron temperatures are treated in a two-temperature model. In addition to this model, a six-temperature model using a multi-vibrational temperature model is adopted. The governing equations for computation are axisymmetric Navier-Stokes equations coupled with species vibrational energy, electron energy and species mass conservation equations. The equations have been numerically solved using the second-order upwind TVD scheme of the Harten-Yee type.
