The local heat transfer by forced convection from the base surface of a bluff obstacle in a variety of configurations was measured. The data are satisfactorily represented by an equation of the type hLkf=C·U∞ρfLμf2/3 The coefficient C depends upon the configuration and the location. Its value is uniformly 0.20 on the rear of a flat-plate strip at 90-deg angle of attack. It diminishes wherever any device can close the dead air space, or reduce its size.

Results of flow field calculations for the collisionless flow of a neutral, monatomic gas past a diffusely reflecting right circular cone at zero angle of attack with the free stream are presented. Singularities at the vertex and at the shoulder of the base are illustrated and discussed. Comparison is made with similar results for spheres and two-dimensional polygonal bodies and with results for transition flow past sharp cones. Methods for improving the analysis are suggested.
