This work is devoted to the validation of modern differential models of turbulence for the calculation of separation in a supersonic flow around the compression wedge. Use is made of the data of experiments for the 25° wedge made by A.A. Zheltovodov at the Khristianovich Institute of Theoretical and Applied Mechanics (ITAM), Siberian Branch (SB), Russian Academy of Sciences (RAS). These data are compared to the results of the three-dimensional and two-dimensional calculations by the use of several differential models of turbulence. A modification of the SST model is proposed that yields an improvement in the quality of the description of the separation zone. The three-dimensional structure of the separation on the wedge is analyzed.
