Optimization of Engine Cylinder Fin by Varying its Geometry and Material

As we all know, Engine cylinder plays a crucial role in running an engine efficiently. Piston reciprocates inside the engine cylinder and the cylinder is subjected to continuous temperature variations and thermal stresses. So cooling an engine cylinder plays an important role to increase the life. Engine cylinder can be cooled by fluids like oil and air as media. To improve the efficiency of air cooling, fins will be provided as they provide the more surface area for heat dissipation. But when we keep increasing the surface area, there are other factors like weight & size will shoot up which will complicate the design of fins and engine cylinder. In order to keep the design simple, thermal analysis is done by varying the size, shape and material of fins. Good thermal conductive materials like LM13 (AL356) and Aluminum alloy, 3D modelling software Pro/Engineer and the analysis tool ANSYS are used for this study. This study will guide us to define the optimum size and shape of the fins to have highly efficient cooling for the complicated designs
