STUDIES OF TRANSIENT HEAT CONDUCTION AT HIGH THERMAL FLUX
Abstract
Results of a theoretical and experimental study of transient heat conduction in cylindrical specimens of copper, Bakelite, stainless steel and graphite, subjected to an incident thermal flux of approximately 500 cal/sq cm-sec. Theoretical investigations included the solution of the transient heat flow equation for cylindrical rods of finite length and with temperature dependent thermophysical properties. Comparisons of this theory, and similar theoretical approaches by other investigators, with experimental results show a large and consistent difference for all materials investigated. The results obtained thus far indicate a serious inadequacy of present heat transfer theory for thermal fluxes of this order of magnitude, and the consistency of these results suggests that a considerably modified theory must be developed to achieve agreement with experiment.
