Abstract
Fins are of great importance in many applications of mechanical engineering, and are widely studied for optimizes the heat transfer between a surface and the ambient. In this paper, we analyze with a routine that employs the Method of Lines from Wolfram Mathematica software the temperature distribution within the fin, to estimate the efficiency of convective straight fins with temperature dependent internal heat effects of radiation, which increases the partial differential equation degree of non-linearity. In order to show the effectiveness of the computational method, the results obtained from a direct study of the effects of some physical parameters are demonstrated in this work, presenting the temperature distribution for a range of parameters values appeared in the mathematical formulation. The proposed method in this work shows that the implemented procedure is very effective and convenient for convective fin problems with an excellent agreement when compared with literature, achieving suitable results of such problems.
