Thermal Analysis and Optimization of Engine Cylinder Fins Using ANSYS Workbench for Enhancing Heat Dissipation in 100cc Engines with Al6061 Alloy

Authors/Creators

Description

Fuel is consumed in the combustion chamber of an internal combustion engine, which is a component of the engine. The engine has a fixed cylinder and a movable piston. Energy is released during combustion, some of which is transformed into useful work and sent to the crankshaft by the connecting rod. The remaining heat is expelled into the atmosphere. If this excess heat is not properly dissipated and remains in the engine, it can cause the engine parts to overheat and become damaged. The cylinder is a critical engine component, subject to significant thermal stresses due to high operating temperatures. 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 over time. Fins, as extended surfaces, facilitate heat transfer but are limited by their length, restricting their effectiveness. The use of porous materials in fins can improve their heat transmission efficiency. Through the use of ANSYS Workbench, this study attempts to increase heat dissipation from the engine cylinder by altering fin geometry. In particular, it looks into heat transfer rates in 100cc engine cylinder fins built of Al6061. By comparing the outcomes, the best fin geometries are found that maximize heat flux and increase engine efficiency and power savings.
