ABSTRACT

The results of a numerical simulation of chemically nonequilibrium air plasma in the heater, nozzle, and underexpanded jets of dissociated and partly ionized air in the VAT-104 high-enthalpy wind tunnel based at TsAGI are presented. The gas temperatures in the induction discharge, flow enthalpy, and flow velocity are computed. The flow over a spherically blunted cone and the heat transfer are considered for the experimental conditions of the VAT-104 wind tunnel. The calculated heat flux and pressure distributions over the cone surface are found to be consistent with the experimental results.
