Comparative Thermal Analysis of Fins

EasyChair Preprint 46

Abstract

In many engineering applications, heat dissipation is an important factor which if not taken care of may lead to high thermal stresses and mechanical failures. The amount of heat dissipated depends on heat transfer coefficient and surface area which can be enhanced by use of extended surfaces i.e. fins. Thermal Analysis of three fins namely Rectangular, Inclined Non-Uniform Perforated, Twin Extension was performed. The models were designed on Creo Parametric 4.0 and the analysis was carried out using ANSYS Workbench 15.0. The fins were analyzed for forced convection. The fins were compared on the basis of non-dimensional Nusselt number and Reynolds number which proved that Twin Extension fin was the most effective among all the three. It was followed by Inclined Non-Uniform Perforated fin.

Keyphrases: Inclined Non-Uniform Perforated Fin, Rectangular fin, Twin Extension fin, heat transfer coefficient
