Abstract: The work is devoted to validation of modern differential models of turbulence on an example of calculation of flow in separation zone arising in supersonic flow around a compression wedge. Experimental data for the 25$^\circ$ wedge, obtained in the ITAM SB RAS by A. A. Zheltovodov, are used. These data are compared with the results of 3D and 2D calculations with the use of several differential models of turbulence. Modification of SST model, allowing to improve the quality of separation zone description, is proposed. 3D structure of the separation on the wedge is analyzed.

Keywords: supersonic flow, boundary layer separation, compression wedge, turbulence model, validation.
