Abstract
The results of numerical investigation of the interaction of a supersonic free stream with the Mach number of 3.85 with a transverse gas jet blown from the surface of an axisymmetric model located at zero angle of attack with respect to the flow are presented. The numerical modeling was conducted using the averaged Navier-Stokes equations employing the k-ω SST turbulence model. The investigation of the influence of the gas jet blowing on pressure redistribution over the axisymmetric model surface and on the formation of an additional transverse force and moment has also been conducted. The shift of the blowing orifice along the model length leads to a significant variation of arising forces and moments. A fundamental difference in the distribution of pressures over the surface at the jet blowing from the axisymmetric body and from a flat plate is shown.
