Finite Element Analysis of Fins with Convection and Radiation Heat Transfer

Abstract

One dimensional analysis of heat transfer from fin is simple when only heat transfer by convectionfrom fin surface. However, in some cases heat transfers by combined phenomena (convection andradiation), this makes the governing differential equation of heat transfer non-linear and the analyticalsolution becomes hard to solve. This paper uses an approximate method to solve the problem withhigh-quality results based on finite element technique. The method can be used for different types offins and for different shapes. The results show suitable agreement between semi-exact solution andnumerical solution
