Three-Dimensional Flow Separation caused by Normal Shock-Wave / Turbulent Boundary-Layer Interaction

  • Conference paper
Symposium Transsonicum III

Summary

Experimental results concerned with the determination of shock-induced separation are presented. The effects of Reynolds number and Mach number are analyzed in terms of topological changes of the separated flow structures. Principles of topological flow analysis are explained. These are used to provide better insight into the complicated three-dimensional separated flow structures. A preliminary discussion of the detected incipient separation is provided. The behaviour of the skin-friction coefficient, displaying a plateau just upstream of the location of separation, is revealed. Boundary layer measurements confirmed by oil-flow visualizations prove that the skin-friction plateau is associated with the three-dimensionality of separation.
