MATHEMATICAL SIMULATION OF THE SUPERSONIC GAS FLOW OVER A WEDGE WITH AN ATTACHED SHOCK WAVE AND HIGH-TEMPERATURE EFFECTS

The development of a supersonic gas fl ow over a wedge in the process of interaction of a plane shock wave with the
wedge was mathematically simulated on the basis of solution of the Euler equations for the nonstationary fl ow of a
compressible inviscid gas in a two-dimensional space with regard for the high-temperature eff ects of ionization and
dissociation of the gas arising in the gas fl ow due to the balanced chemical reactions proceeding in it. The results of
solution of the problem on the supersonic gas fl ow over a wedge within the framework of the perfect-gas and real-gas
models were compared. The infl uence of the high-temperature eff ects in this fl ow on its characteristics and the angle
of inclination of a shock wave in it to the wedge was investigated.
