INFLUENCE OF THE HIGH-TEMPERATURE EFFECTS IN A NOZZLE WITH A NONSTATIONARY LOCAL POWER SUPPLY ON THE GAS FLOW IN IT

A simulation of a high-temperature air fl ow in a nozzle with a nonstationary local power supply has been performed. The thermodynamic processes in this fl ow were simulated using an approximate model of equilibrium air thermodynamics. Results of a numerical simulation of one-dimensional fl ows in nozzles with a moving powersupply zone, used in alternating-current plasma generators, are presented. On the basis of the numerical-simulation data obtained, the qualitative patterns of the gasdynamic and thermal processes proceeding in such a nozzle with a nonstationary power supply were analyzed. The results of calculations performed on the basis of the ideal-gas and real-gas models with regard for the physicochemical processes occurring in a real gas at a high temperature were compared
