Abstract

The present study is to investigate the effects of upstream blowing jet on the compressible convex-corner flows. The characteristics of mean and fluctuating pressure distributions are associated with the type of expansion flows, blowing rates, and porosity. Even small amounts of upstream blowing tend to delay the transition of subsonic and transonic expansion and reduce the levels of downstream surface pressure fluctuations in subsonic interactions. The intensity of surface pressure fluctuations is associated with blowing rates for the separated flows. Larger blowing rates result in upstream movement of shock wave and enhance the flow unsteadiness (or peak surface pressure fluctuations) near the corner.
