Design and Thermal Analysis of Fins for Air Cooled Engine by Varying its Geometry
Abstract: An air-cooled motorcycle engine releases heat to the atmosphere through the mode of convection to facilitate this, fins are provided on the outer surface of the cylinder. The cooling fins allow the wind to move the heat away from the engine. The heat transfer rate depends upon the velocity of the vehicle, fin geometry and the ambient temperature. Low rate of heat transfer through fins is the main problem of …
