Scaling of Incident Shock-Wave/Boundary-Layer Interaction at Expansion Corner

Shock-wave/boundary-layer interaction (SWBLI) involving expansion waves is a common and complex phenomenon in high-speed inlets, where accurate prediction of interaction length is crucial for detecting separation. Traditional scaling laws based on inviscid pressure ratios fail to capture expansion waves effects, causing significant errors in real flight conditions. This study undertakes both experimental and theoretical investigations into the interaction between an incident SWBLI and expansion
