Abstract

The present study aims to investigate this three-dimensional nature of shock–boundary-layer interaction in the presence of side walls and in the vicinity of an expansion corner at a freestream Mach number of 3.9. The major objectives, therefore, are to study the effect of variation in the geometrical parameters such as 1) the wedge angle (α=6, 10, and 14 deg), 2) the expansion corner angle (β=6, 10, and 14 deg) and, 3) the inviscid impingement location xi with respect to the expansion corner on the overall interaction (xi=0 and ±4δ). The effect of the three parameters on the interaction is studied using surface oil-flow visualization and mean pressure measurements along the centerline of the model.
