Computational investigation of heat transfer on the surface of engine cylinder with fins of different shapes and materials

Abstract

In everyday life the use of vehicles has expanded immensely for some ventures and house hold applications, likewise the running time of engine cycle is exceptionally long. Thus because of the consistent running enormous measure of heat is produced. At the point when this heat isn't appropriately disseminated, the engine gets more fragile very soon and life of the engine declines because of the heat development. To build the life of the engine, heat dispersal is expanded by giving fins at external of engine chamber. The shape of the fins and the material used for the fin increases its heat dissipation capacity and in turn increases the cooling of the engine for proper functioning. The present work focuses on the design of fins of circular and tapered shapes for a 2-stroke engine. The temperature distribution and the heat dissipation along the fin surface of two shapes has been observed by a steady state thermal analysis. Alusil and Silumin has been selected as the fin materials and a computational evaluation has also been done using FEM. A better shape of the fin along with a suitable material has been selected based on the results observed by FEM and on comparison with the existing shape and material of the fin.
