Optimization of Thermal Analysis of Engine Cylinder Fins by Varying Geometry

Abstract

Heat transfer by convection between a surface and the fluid surrounding can be increased by attaching to the surface called fins. The heat conducted through solids, walls, or boundaries has to be continuously dissipated to the surroundings or environment to maintain the system in a steady state condition. The cylinder of the engine is one of the key components of the vehicle and is prone to maximum temperature variation and thermal stress. To cool the cylinder, the cylinder fin is designed to improve the heat transfer rate. Thermal analysis is done on the engine cylinder fins; it is very useful to understand the heat dissipation in the cylinder. The idea applied in this project is to increase the heat dissipation rate by using intangible working fluid, just air. It is understood that the heat dissipation rate is increased by changing the surface region; therefore, it is very challenging to design such a huge complicated engine. In this project, the analysis of the engine fin is carried out for different geometries such as Rectangular, Triangular, convex, and Tapered fin. A 3D model is created in SolidWorks and analysis is done using ANSYS Software in steady state condition. The material used for the fin body is Al6063. The result is compared to find the best geometry which gives the maximum heat flux.
