This paper presents the validation problem for the numerical determination of gas dynamic parameters in the supersonic flow of a turbulent hot jet into a flooded space. The computational scheme used is based on the two-parameter Menter model modified in terms of the determination of the turbulence generation term, supplemented by the Sarkar compressibility correction with correction for small values of the turbulent Mach number. Gas dynamic parameters of the flow along the jet axis are compared with experimental data of Seiner and results of numerical modelling of other authors. The k-ω SST turbulence model with a modified Sarkar compressibility correction shows better agreement with the experimental data results than turbulence models with the standard version of this correction.

The paper presents a classical validation problem of high-speed modeling. This problem is about interaction of a shock wave with a boundary layer in a laminar air flow around a cylindrical–conical body and a double cone. The main computational complexity of this problem is the detailed resolution of the near-wall region in order to further reproduce the experimental distributions of the surface characteristics of pressure and heat flux. Depending on the conditions of the undisturbed flow of the researched flow mode, the problem can have a recirculation zone, which is a vortex flow. This flow has a significant effect on the structure of the near-wall flow.
