Analysis of Temperature Distribution And Performance of Motorcycle Engine Fins

Abstract

Air-cooled motorcycle engines release heat into the atmosphere through the process of forced convection, an important component for increasing the convection heat coefficient and the rate of heat transfer is fins. The rate of heat transfer depends on the geometry of the fin, the surface of the fin, the thickness of the fin, the distance between the fins, the temperature of the environment, and the air velocity. The research was conducted by varying the air velocity with the addition of holes in the geometry of convex fins. The main purpose of this study was to analyze the rate of heat transfer that occurs in the geometry of perforated fins by varying the air velocity. Physical models are designed using the Autodesk Inventor Professional 2020 application and simulated by Dynamics 2019 Autodesk Computational Fluid. The result of 4mm perforated convex geometry analysis is better than 2mm and 6mm perforated fins and non-perforated. Due to this, the rate of heat transfer has increased so that the coefficient of convection heat transfer increases and the decrease in the temperature of perforated fins is consistently higher than non-perforated fins, improving the efficiency and effectiveness of motorcycle fins so that the performance of motorcycle engines also increases indicated by the temperature distribution
