Numerical Solution of Transonic Normal Shock Wave-Boundary Layer Interaction Using the Bohning-Zierop Model

摘要

A numerical method for transonic shock wave-boundary layer interaction on a plane wall or on a convex wall, based on the Bohning-Zierep (BZ) model where a turbulent boundary layer is perturbed by a weak normal shock wave that exists in the external flow is described. The flow region along the wall is divided into a relatively thick upper layer, where the flow is considered to be inviscid and rotational, and a thin sublayer where the flow is viscous. The problem of the diffusion inside these layers of the jumps in flow quantities across the shock wave is solved without the practical disadvantages of the BZ method. Compared to experiments, good agreement is obtained if the Mach number in front of the shock wave does not exceed unity too much.
