Abstract:

The report provides a summary of theoretical and experimental research on turbulent boundary layers under supersonic free stream conditions. The program included investigations of boundary layer behavior at various Mach Numbers for smooth, adiabatic surfaces, various types of surface roughness, and the combined effects of roughness and heat transfer. The experimental program involved velocity profile measurements and the momentum deficit method of calculating skin friction, determinations of local shear stress values, and the utilization of plug-type calorimeters for determinations of heat transfer rates.
