Abstract : Local flow conditions, recovery factors, and heat-transfer coefficients were determined experimentally on the hemispheric nose of a hemisphere-cylinder with a laminar boundary layer at M=2.8. Results indicated that the recovery factor may be expressed by the square root of the Prandtl number even in the presence of a pressure gradient. An analysis of the supersonic heat-transfer data revealed that the supersonic values obey a law almost identical to that derived from incompressible theory.
