Turbulent boundary-layer heat transfer and skin-friction coefficients were measured on sharp slender cones at a free-stream Mach number of 5.0. Wall-to-stagnation temperature ratios from 0.15 to 0.80 were obtained by precooling or preheating the model. Tests were conducted for a wide range of Reynolds numbers by varying the tunnel supply pressure and temperature, thus providing data for naturally turbulent boundary layers. The experimental results were compared with existing theories which predict convective Stanton number or skin-friction coefficients. These comparisons indicate that the heat-transfer data are best predicted by the Spalding-Chi law and the skin friction by the Sommer-Short reference temperature method. The experimental Reynolds analogy factor is adequately predicted by Colburn's incompressible correlation for wall-to-stagnation temperature ratios above about 0.5. However, for lower wall temperature ratios, the experimental Reynolds analogy factor decreases with decreased temperature ratios in a manner which has not been previously reported. (Author).

Abstract: The method presented in NACA TN 2692 for evaluating the skin friction of a turbulent boundary layer in compressible flow on an insulated surface is extended to evaluate the turbulent skin friction and heat transfer in compressible flow on a surface which is heated or cooled. The results of this analysis are in good agreement with the heat transfers measured in flight on the NACA RM-10 missile up to Mach number of 3.8.

The effects of the injection of a light, medium, and heavy gas on the skin friction and heat transfer characteristics of the laminar boundary layer flow over a flat plate were investigated. This was done by a numerical solution of the governing differential equations for injection rate parameters of -0, -0. 1, -0.2; Mach numers from 0 to 3; and wall-to-stream temperature ratios of 0.25, 0.50, and 1.00. The results show that the selection of discrete injection systems must represent a favorable compromise between conflicting factors (such as small molecular weight and large molecular diameters) which influence the amount of reduction in skin friction and heat transfer desired.
