Investigation for Thermal Relation Between Connecting Rod and Fins through Thermal Analysis of a Triangular Fin Made of Various Materials

Abstract

This paper explores the analysis of heat transfer through non-uniform geometries, specifically focusing on an I section and triangular fin configurations. Boundary conditions, such as constant temperature or uniform heat flux at the base and fully insulated or convective conditions at the tip, were applied to both the I section and the fin. Thermal analysis utilized the Fourier law, the first law of thermodynamics and Newton's law of cooling for both the I section and triangular fin. Analytical solutions were derived for conduction and convection, with the latter employing Bessel functions for the triangular fin. The study considered materials such as copper, aluminium, brass, cast iron and steel and various parameters such as heat flux, temperature distribution, fin effectiveness and fin efficiency were analysed. To present the findings, graphs depicting the analysed parameters were generated using Microsoft Office Excel 2016. The material properties were assumed to be isotropic throughout the analysis.
