Comparison of Fins in IC Engine Using CFD Analysis

The purpose of this study is to compare the impact of fin shapes on the basis of effectiveness for better heat transfer characteristics of engine. In this study computational fluid dynamics (CFD) is used to simulate different fin shapes during running condition (40 km/h) after applying boundary conditions of an IC engine (temperature is 873 K). The observation demonstrated how temperature and heat transfer coefficient are going to change according to different fin shapes that will help in obtaining better fin shape for an IC engine. Four types of fin profiles (Rectangular, Circular, Triangular and Trapezoidal) are analyzed in this study for two cases. In case 1, base area and the length of fins are equal for all profiles and in case 2, base area and surface area of all fins are equal. In this study, effectiveness of different fin profiles is calculated and compared in two cases.
