Aerodynamic Heating and Convective Heat Transfer—Summary of Literature Survey

Abstract

The analytical and experimental information appearing in the literature for convective heat transfer at high velocities is summarized. Particular emphasis is given to heat transfer for submerged flow over flat plates, wedges, cones, and cylinders with a single reference to flow in pipes. The evidence presented supports, as a fundamental heat-transfer relation, the modified Newton’s law of cooling $q=hA[tw−(to+ruo2/2gJcp)]$ where the term ru_o²/2gJc_p) accounts for the influence of frictional dissipation and is readily evaluated when the recovery factor r is known. A second and very important result is the evidence given to show that the heat-transfer coefficient h, is independent of the magnitude of the frictional-dissipation term. Data are presented for the recovery factor and heat-transfer coefficient for high-speed subsonic- and supersonic-flow velocities. It should be noted, however, that heat transfer by radiation is not considered here as it would be treated in the usual manner for heat transfer without frictional dissipation.
