Temperature Distribution and Efficiency of a Single Sheet of Radiative and Convective Fin Accompained by Internal Heat Source

Abstract

When the finned heat-transfer surface is used for heat exchangers, space radiators, or nuclear fuel elements under high temperature, there are some cases when the fin emits radiative and convective energy and are accompanied by internal heat source. There are some reports on the simple behavior of finned heat-transfer surface. But the mutual heat-transfer mechanism of fins has not yet been analysed. This report gives an analysis of the radiative and convective surface accompanied by an internal heat source. The steady state conduction equation is introduced, and solved numerically by the digital computer. Temperature distribution, efficiency and heat-transfer ratio are calculated. Various figures are introduced.
