Thermal Analysis of Engine Cylinder Fins by Varying Fin Geometry and Material
Abstract
Internal combustion engines generate a large amount of heat during combustion. Excessive temperature inside the engine cylinder can lead to lubrication failure, component deformation, and reduction in engine efficiency. To maintain an optimum operating temperature, cooling systems are employed in engine design. In air-cooled engines, extended surfaces known as fins are used to enhance the heat transfer rate from the cylinder surface to the surrounding atmosphere. The present study focuses on the thermal analysis of engine cylinder fins with different geometries, thicknesses, and materials using finite element analysis. Square and circular fin geometries with thicknesses of 2 mm and 3 mm are analyzed using Aluminum Alloy 6061 and Magnesium Alloy as fin materials. The models are designed using Fusion 360 and analyzed using ANSYS Workbench under transient thermal conditions. Parameters such as temperature distribution, total heat flux, and directional heat flux are evaluated. The results indicate that circular fins with Aluminum Alloy demonstrate better heat transfer performance compared to other configurations. The study concludes that fin geometry and material selection play a significant role in improving cooling efficiency and reducing thermal stresses in air-cooled internal combustion engines.
