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