Abstract: Nowadays, it is common knowledge in the car industry that in order to increase vehicle economy, heat dispersion throughout the engine must be naturally cooled. The heat transfer properties of this fin of various shapes will be researched using CFD simulations and fabrication of the best design to validate the results. Different fins of circular, triangular, and parabolic form are explored in this study to achieve the best heat dissipation shape for an engine. Fins are primarily used to improve the rate of heat transfer to the surrounding environment by boosting convection. Conduction, convection, and radiation all contribute to the quantity of heat transmission. The heat transfer rate rises as the temperature differential between the objects grows. Our project's major goal is to improve heat transfer rates using several types of fin (circular, triangular, and parabolic) arrangement geometry. CATIA software is used to create the 3D model. The results and conclusions will be drawn when the experimental testing is completed.
