Exhaust system has vital role in performance of IC engine which can significantly affect the fuel consumption, exhaust smoke emission and temperature. The objective of current research is to investigate the heat transfer characteristics of exhaust manifold incorporated with fins. The CAD design of the exhaust manifold is developed using Creo design software and its thermal analysis was conducted using the ANSYS v21 simulation package. The CFD analysis is also conducted to determine the effect of fins on heat transfer characteristics of exhaust manifold. Thermal characteristics of exhaust manifold system using CFD have shown an enhancement of heat dissipation capability by 3.01%. The incorporation of fins augmented turbulent flow which enhanced heat dissipation capability of exhaust manifold with 2.42% reduction in maximum temperature.
