Abstract: A mathematical approach is proposed and the numerical results are presented for the problem of computer simulation of a separated turbulent flow in the vicinity of the right step. The kineticalconsistent finite-difference gasdynamic schemes are involved for computations. The computational results for Mach numbers $\mathrm M=2;2,95;4$; $\mathrm{Pr}=0,71$ and $\operatorname{Re}_{\delta}=1,6\times10^5$ are compared with the data of the natural experiments and analytical results.
