- Abstract
A numerical simulation of gas flows in the nozzle of an alternating-current plasma generator with a nonstationary local energy supply has been performed. The nonstationary gas flows in the plasma-generator nozzle with a highpower energy supply were simulated using the finite-volume method and the vectorized approach to the calculation of flows. Results of numerical simulation of the one-dimensional and two-dimensional gas flows in the nozzle of an alternating-current plasma generator with a moving energy-supply zone are presented. On the basis of the numericalsimulation data obtained, a quantitative analysis of the gasdynamic and thermal processes occurring in the nozzle of such a generator with a nonstationary energy supply to the gas flow in it has been performed. The dependence of the rate of an overexpanded gas flow in the plasma-generator nozzle and the shift of a compression shock in it on the power and cyclicity of the energy supply to the subsonic section of the nozzle was determined.
