Abstract

This paper addresses the turbulent airflow in 2D and 3D channels of rectangular cross section with weak breaks of walls. Flow regimes with supersonic velocities at the inlet and downstream of the break of the lower wall are examined. Solutions of the unsteady Reynolds-averaged Navier-Stokes equations are obtained with finite-volume solvers ANSYS-15 CFX, Fluent and SU2. A significant hysteresis in the dependence of the shock wave position on the Mach number is demonstrated. The existence of the hysteresis is explained by a shock wave interaction with the supersonic zone located downstream of the break of the lower wall. Refs 17. Figs 5.
