The effects of wall cooling and nose bluntness on laminar and transitional reattaching flows induced by a 9.5-degree ramp were investigated at Mach numbers from 3 through 6 measuring the longitudinal surface pressure and heat-transfer rate distributions, as well as the flow-field pressures, at several longitudinal stations. Reynolds number based on flat-plate length was varied from 0.25 to 1.0 million. The trend in the change in interaction length with Reynolds number increase indicated laminar reattachment at all test Reynolds numbers at M 6 and transitional at the two higher Reynolds numbers at M 3.
