Heat Dissipation Analysis and Optimization of Engine Cylinders Fins of Varying Geometry Using ANSYS Workbench

Abstract

The cylinder is a critical component at the engine's core, susceptible to significant thermal stresses due to high operating temperatures. Fins are extended surfaces attached to an object or surface, designed to enhance the heat transfer rate between the surface and the surrounding fluid by increasing the effective heat transfer area. Fins are modifications on the external surfaces of objects, which, by increasing convection, the heat transfer rate with the material cylinder fins are designed to enhance heat dissipation and improve the engine's thermal management. Thermal analysis of these fins is crucial for understanding heat dissipation within the cylinder over time. Fins are usually used on the fixed surface to extend the surface and increase the transfer rate. Fins, as extended surfaces, facilitate heat transfer but are constrained by their limited length, which restricts their effectiveness in dissipating heat. Enhancing heat transfer efficiency in fins can be achieved using porous materials. This study focuses on increasing heat dissipation from the engine cylinder by varying fin geometries using ANSYS Workbench. Specifically, the research investigates 100cc engine cylinder fins made of Al6061 to analyze heat transfer rates. The results are compared to identify optimal fin geometries that maximize heat flux, enhancing engine efficiency and power savings.
