Abstract : Measurements of heat transfer rates on cone-cylinder models and in the separated regions behind an axially symmetric backward facing step are reported. The measurements were obtained in the shock tube at flow Mach numbers between 1.4 to 2.5. The heat transfer in the separated region is studied for variation of the flow Mach number from the supersonic values obtained in the shock tube to the hypersonic value obtained in the shock tunnel. The position of the maximum heating rate is noted for step height and forebody length. It is found that the point of maximum heating moves downstream with increasing step height while increasing forebody length causes an upstream movement of this point.
