An experimental investigation of the shock wave turbulent boundary layer interaction
Abstract
Interaction between a shock wave and a turbulent boundary layer was studied. The boundary layer was formed on the floor of a wind tunnel and compression corner models were used to generate the oblique shock wave. Full range of possible flowfields, including flow with no separation, flow with incipient separation, and flow with a significant amount of separation were generated. Measurement techniques used included Schlieren photography, surface static pressure measurement, surface streak pattern measurement, and laser Doppler velocimetry. The results of the LDV measurements indicated that the boundary layer was significantly altered by the interaction. Several features of the redeveloping flow, including high rates of boundary layer growth, large Reynolds stress values, and large turbulent triple product values, indicated the presence of large scale turbulent structures within the turbulent boundary layers downstream of the shock wave boundary layer interactions.
