Abstract

This paper presents a numerical simulation of the flowresulting from transverse jet injection into a supersonic flow througha slot nozzle, at different pressures in the injected jet and mainflow. Calculations on grids with different resolutions use theSpalart--Allmaras turbulence model, the $k$--$\varepsilon$ model,the $k$--$\omega$ model and the SST model. Based on a comparison ofthe calculated and experimental data on pressure distribution on thewall, the length of the recirculation area and depth of penetration ofthe jet in the supersonic flow, conclusions are made about the accuracyof the calculation results of the different turbulence models and theapplicability of these models for solving similar problems.
