Abstract

Turbulent properties in the shock wave/turbulent boundary layer interaction induced by blunt fins with semi-cylindrical leading edge have been investigated. Flow fields are visualized by the Schlieren method and the oil flow technique. Pressure fluctuations are measured in the whole interaction region in order to understand the phenomena and provide sufficient information for turbulent modeling. Distributions of standard deviations and higher moments of pressure fluctuations are also measured. Quite complicated distributions of standard deviations and higher moments of pressure fluctuations are obtained. Those properties show significant changes in the interaction region and quite interesting characteristics are observed. Also in tire interaction region intermittent phenomena due to the shock wave motion are observed. Those complicated results suggest that more sophisticated turbulent modeling is necessary to simulate the flow field.
