N2 - Positions of shock waves in the 2D channel with a central body are studied numerically. Solutions of the Euler equations and Reynolds-averaged Navier–Stokes equations are obtained with finite-volume solvers. Numerical simulations reveal a considerable hysteresis in the shock wave position versus the supersonic Mach number given at the inlet for inviscid gas and for viscous gas. In the certain range of inlet Mach number, there are asymmetrical solutions of the equations. Small change in the geometry of the channel leads to shift of the hysteresis range.
