DESIGN MODIFICATION AND ANALYSIS OF TWO WHEELER COOLING FINS

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.Insufficient removal of heat from engine will lead to high thermal stresses and lower engine efficiency.The cooling fins allow the wind to move the heat away from the engine.Low rate of heat transfer through fins is the main problem of air cooling system.An attempt is made to simulate the heat transfer for different materials and geometry of fins to analyze effects on rate of heat dissipation from fins surfaces.The heat transfer surfaces of Engine are modelled in ANSYS, and the main aim of this work is to study different materials and geometry of fins to improve heat transfer rate by changing fin materials u under different conditions.
