It is important for an air-cooled engine to utilize fins for effective engine cooling to maintain uniform temperature in the cylinder periphery. Many experimental works has been done to improve the heat release of the cylinder and fin efficiency. In this study, heat release of an IC engine cylinder cooling fins with six numbers of fins having pitch of 10 mm and 20 mm are calculated numerically using commercially available CFD tool Ansys Fluent. The IC engine is initially at 150 and the heat release from the cylinder is analyzed at a wind velocity of 0 km/h. The heat release from the cylinder which is calculated numerically is validated with the experimental results. With the help of the available numerically results, the design of the I.C engine cooling fins can be modified for improving the heat release and efficiency.
