The influence of the entropy layer generated by the blunted-plate leading edge on the flow over a single fin or pair of fins installed on the plate is studied experimentally and numerically. Experiments are carried out in a Ludwieg-type wind tunnel at Mach numbers of M = 5 , 6, and 8 and Reynolds numbers from 7 × 10 6 to 27 × 10 6 at turbulent, transitional, and laminar boundary layers on the plate in front of the fins. Panoramic optical methods are used for measurements of heat flux and pressure. Flow visualization is done as well. It is shown that even a small blunting of the plate leading edge considerably changes the heat transfer, pressure, and shear-stress distributions at the shock wave/boundary-layer interactions; and, under certain conditions, it causes changes of the flow structure.
