EFFECT OF SUBLIMATION ON STAGNATION POINT HEAT TRANSFER

Abstract

The reduction of heat transfer to carbon dioxide models caused by the subliming solid was measured experimentally. Heat transfer coefficients were obtained for 0.7-cm-diam copper and carbon dioxide hemisphere-cylinders in air at 500 to 800 C moving at 100 to 300 cm/sec. The ratios of the subliming to the non-subliming coefficients were higher than the theory at high mass transfer rates. At 0.0084 gm/sq.cm-sec, which was the highest mass transfer rate obtained, the heat transfer rate was reduced by 65%. (Author)
