Turbulent 2D airflow in a bent convergent-divergent channel is studied numerically. The free stream is supersonic and parallel to the lower wall of channel. Solutions of the unsteady Reynolds-averaged Navier-Stokes equations are obtained with an open-source finite-volume solver SU2. The solutions demonstrate an expulsion/swallowing of the shock waves with variation of the free-stream Mach number Flow topology in the channel and in front of its entrance is discussed. The hysteresis of shock wave positions with variation of is determined.
