Effect of heat Transfer Through Arbitrary Shaped fins using Computational Fluid Dynamics

Abstract

An automobile engine produces a lot of heat and is subjected to thermal stresses. These high temperatures and thermal stresses generated might cause distortions in the engine components and also reduces the volumetric efficiency of the engine. It is important to remove this heat generated to ensure the ideal functionality of the engine. In order to dissipate this heat out of the engine through convection, extended surfaces(fins) are used as a medium, projected to the engine walls. In the present analysis, arbitrary shaped fins of same surface area are designed and heat transfer analysis is performed. Using the ANSYS Fluent software the analysis is done. The main intent of our study is to increase the heat transfer rate using the arbitrary shaped fins. The results obtained are compared with the regular shaped solid fins. Results show there's a significant increase in heat transfer through the arbitrary shaped fins. The fin with elliptical hole has greater heat transfer rate than other models of fins used in the analysis.
