Two-Dimensional Fin Performance: Bi (Top Surface) Greater Than Equivalent to Bi (Bottom Surface)
This paper presents the results of an investigation of unequal convection coefficient effects on the heat lost from a fin. Heat balance integral approaches have been applied to this two-dimensional problem with useful results for the heat transfer but only approximate results for the temperature distribution (Steir, 1976). Thus the purpose of this note is to provide additional insight into the effects of unequal top, bottom, and tip surface convection coefficients. This difference will be denoted by the Biot numbers Bi rather than the convection coefficients.
