Structural and Thermal Simulation of Fins Of An Air Cooled Engine Cylinder Under Varying Speed Conditions
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2014, Vol 2, Issue 9
Abstract
Engine cylinder is the main component of the automobile which is subjected to high temperature variations and thermal stresses. Fins are basically mechanical structures which are used to cool various structures via the process of convection. An air-cooled motorcycle engine releases heat to the atmosphere through the mode of forced convection. To facilitate this, fins are provided on the outer surface of the cylinder. The heat transfer rate depends upon the velocity of the vehicle, fin geometry and the ambient temperature. Many experimental methods are available in literature to analyze the effect of these factors on the heat transfer rate. In the present paper an effort is made to study the effect of fin parameters on fin array performance which includes variation in pitch, thickness and fin material. The heat transfer surface of the engine is modeled in CATIA V5 R20 with varying thicknesses and fin spacing and simulated in ANSYS software. An expression of average fin surface heat transfer coefficient in terms of wind velocity is obtained. Heat transfer is taken as input for structural analysis. Finally obtained temp distribution, heat flux ,thermal stresses and deformation for three types of materials like aluminium, cast iron and copper.
