Conference paper


Triple-shock configurations and vortex structures are researched in problems of control of a high-speed flow past an aerodynamic body “plate-cylinder” at freestream Mach number M = 4. The effect of an energy source dislocated in the incoming flow ahead of a bow shock is evaluated for the gaseous media of different physical–chemical properties in a range of the ratio of specific heats γ from 1.1 to 1.4. The energy source is modeled as a heated rarefied channel. Changing the angles in triple-shock configuration and the effect of the stagnation pressure decreasing together with the front drag force reduction is studied depending on γ and rarefaction factor in the energy source. Generation of the Richtmyer–Meshkov instability accompanied the forming of the triple configuration is modeled for M = 8. Complex conservative difference schemes are used in the simulations.
