Thermal analysis of fin materials for engine cylinder heat transfer enhancement

Abstract

In automobiles the internal combustion engine cylinder is one of the major component which is subjected to high thermal stresses and temperature variations. Engine cylinders come up with fins or extended surfaces. The heat transfer enhancement from engine cylinder is mainly depends on fin material and shape. We can use different fin materials and fin geometries in order to increase heat transfer rate. In this work heat transfer rate through fins with different materials was evaluated. The fin geometries such as the rectangular fins attached to the cylinder block. In this analysis different physical and thermal properties along with cost associated with the fin materials are considered. The 3D model of geometries are created using CATIA-V5, and thermal properties are analyzed using commercial software ANSYS FLUENT 2020 R1. From the results of steady state thermal analysis of engine cylinder it is found that the value of heat flux increased through cylinder block to the surroundings. The weighted point method applied to find performance of fins based on material that is best suited for manufacturing of fins.
