Abstract:
A review is made of the existing knowledge about the interaction of impinging shock waves with laminar or turbulent boundary layers, to emphasize and illustrate that the relative degree of inviscid-dominated solid wall-like reflection behavior versus viscous-dominated free surface-like reflection is a major feature determining the disturbance flow pattern. This idea is then used to appraise existing transonic normal shock-boundary layer interaction experiments and establish an ordered relationship between them. As a result, it is shown that far from being unusual, a post-shock pocket of supersonic flow supersonic tongue is in fact a common feature of all such interaction patterns, although its scale can change drastically with incident shock strength, Reynolds number and downstream conditions.
