AN EXPERIMENTAL EVALUATION OF THE INSULATED-MASS TECHNIQUE OF MEASURING HEAT TRANSFER AT HIGH VELOCITIES,

Abstract

An experimental evaluation was made of the insulated-mass method of measuring heat transfer rates in air flows at supersonic speeds. This method consists of measuring the rate of change of temperature with time of an insulated mass of known heat capacity. Wind tunnel tests of a flat plate model at Mach Number 5.01 were made to determine the effect of several qualities of insulation. The tests indicated a strong influence of insulation on the results, but a suitable insulation was obtained and satisfactory heat transfer coefficients were obtained. A survey of heat transfer along the flat plate was made and the results are compared with turbulent flow theories. (Author)
