Analysis of Rectangular Fins Using CFD

Abstract

The engine cylinder is one of the most important vehicle components that is exposed to extreme temperature changes and thermal stresses. Fins are placed on the cylinder's surface to increase the rate of heat transfer and thereby cool the cylinder. The heat dissipation inside the cylinder can be determined by performing thermal analysis on the engine cylinder fins. Since we know that raising the surface area increases the rate of heat dissipation, designing such a massive, complex engine is extremely difficult. The main goal of this paper is to use ANSYS WORK BENCH R 16 to investigate the thermal properties of cylinder fins by varying their geometry, content, and thickness. The thermal analysis determines temperatures and other thermal quantities that vary over time. Many applications, such as cooling, are interested in the variance of temperature distribution over time. The accurate thermal simulation could help identify important design parameters for longer life. Presently Material used for manufacturing cylinder fin body is Aluminum Alloy A6061 which has thermal conductivity of 160-170W/mk. Currently, tests are being conducted on cylinder fins made of this material as well as Aluminum alloy 6061, which has higher thermal conductivities.
