Heat Transfer and Fin Performance Comparison between Constructal T-shaped Porous and Solid Fin

Abstract

In this literature, constructal theory is applied to compare the heat transfer rate and the fin performance between a T‐shaped porous fin and that of solid fin, which are exposed in a convective environment. Adomian decomposition method has been applied for solving governing equation of stem and flange part of the fin. This method provides an explicit form of analytical solution from which temperature distribution and performance analysis can easily be performed. Though the fin performance parameters are reduced a little bit but heat transfer rate can be enhanced as compared to solid fin under same geometric and flow conditions.
