Abstract

The problem of natural convection from a vertical heat-generating fin is solved by coupling the equation of thermal diffusion in the fin to the constitutive equations of the ambient medium under laminar flow conditions. The analysis is accomplished by employing an integral method. For the range of values of the fin parameter and the strength of the heat source considered in the analysis, the numerical results are rendered into a correlation equation for the average Nusselt number as a function of the fin parameter and the strength of the heat source.
