Transverse Injection of a Jet from the Surface of a Flat Plate into the Supersonic Flow Over it

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

A numerical simulation of a supersonic two-dimensional gas flow into which a gas jet is injected from the surface of a fl at plate along the normal to it has been performed. The calculations were carried out using the Reynolds-averaged Navier–Stokes equations closed by the SST model of turbulence. The influence of the pressure ratio of the jet on the structure of the flow formed as a result of its injection into the supersonic crossflow, the angle of inclination of the head shock wave, the length of the separation zone, and the depth of penetration of the jet into the main flow were determined. The results of calculations performed for different Mach numbers of the main flow and different pressure ratios of the injected jet were compared with the corresponding results of a physical experiment. The data obtained can be used for optimization of the mixing of the injected jet with the main supersonic crossflow.
