Heat transfer at the lateral surface of a blunt cone during the absorption of the entropy layer by a laminar or a turbulent boundary layer

The effect of entropy layer absorption on the aerodynamic heating of a blunt round cone with a half-angle of taper of 10 deg is investigated experimentally and analytically for Mach 6.1 and 8. Similarity parameters are obtained for heat transfer under conditions of entropy layer absorption by a turbulent boundary layer. The experimental and analytical results are processed in terms of similarity parameters for laminar and turbulent boundary layer flows. The results are then used to obtain interpolation formulas for the heat transfer parameter.
