DESIGN AND FINITE ELEMENT ANALYSIS OF TWO WHEELER ENGINE FINS

In India, generally in two wheelers air cooled engines are used. For this purpose, extended surfaces i.e. fins are used, which are mounted on cylinder block and cylinder head. Though the efficiency of cooling in air cooled system is less as compared to the water cooled system still it is used because of less space available to keep accessories. In this project the extended surfaces i.e. fins of Honda Sh ine & Bajaj Discover two wheeler automotives are tested to investigate effect on heat transfer rate by changing the Cross - section, Fin Pitch, Fin Material and Fin Thickness. The vehicles considered have single cylinder air cooled engines with set of rectan gular fins mounted on the cylinder block. Through experiments temperature generated at steady state condition have been measured from the fin surface and using the value as key parameter, heat dissipated and heat flux through fin is calculated using empiri cal formulations. The same data is then validated by using FEA approach.
