DESIGN AND STUDY THE EFFECTIVENESS OF ENGINE CYLINDER FIN WITH VARIABLE GEOMETRY AND MATERIAL

Abstract

In automobiles, the engine cylinder is subjected to high temperature variations and thermal stresses .So as to cool the engine cylinder, fins are mounted on the engine cylinder to increase the rate of heat transfer. By doing thermal analysis on the engine cylinder fins you can know the rate of heat transfer inside the cylinder. The main objective of the project is to analyze the thermal behavior of cylinder fins by varying geometries, materials and thickness. In this project 2.5 mm and 3mm thickness of fins are considered for various fin geometries and they are designed using AUTO CAD 2016.Thermal analysis on the fins is done by using ANSYS WORKBENCH. In our project we have taken materials aluminum alloy 6063 and aluminum alloy 7068 instead of general material aluminum alloy 204. The geometries circular, rectangular and trapezoidal fins with Aluminum alloy 204, Aluminum alloys 6063 and 7068 of thickness 2.5mm &3mm are compared on the basis of total rate of heat flux & effectiveness. It is found that aluminum alloy 6063 of circular geometry with 2.5 mm thickness is having more rate of heat flux &effectiveness.
