ABSTRACT

Results predicted by two calculation methods (the method of the effective length and the Cebeci-Smith algebraic model of turbulence) are compared with experimental data on the heat flux distribution over the surface of a hemisphere at the Mach number M = 5. A modification of the Cebeci-Smith turbulence model is proposed.
