Abstract Fins increases the heat transfer from a heat generated device by increasing the surface area of it. Fin with holes or perforated fins increases the surface area available for heat removal but also increases the intensity of the air flow, which further increases the heat removal. A two wheeler engine with fins having circular perforation has been designed in the present work. ANSYS 16.0 has been utilized to solve present analysis. Al6063 and Nickel as a material have been considered to see its effect on the heat transfer rate. Perforation has been done to see its effect on the heat transfer. Results of perforated fin engine have been compared by engine without perforated fins. Time-temperature cooling curve has been plotted and results reveal that perforation increases the heat transfer. From the results it also been noticed that Nickel shows larger heat transfer rate compared to Al6063. Weight analysis has also been conducted in the present work. Engine having perforated fins weigh 1.0772 kg for Al6063 and 3.5507 kg for Nickel, but engine with solid fins weigh 1.0798 kg for Al6063 and 3.5593 for Nickel, which reveals that engine made of Nickel weigh more than three times when compared with engine made of Al6063.
