Abstract: In this thesis, an exhaust manifold modelled by PRO-E design software. The thesis will focus on CFD and thermal analysis with different loads (2, 6,12,14,16 and 18 kg). Thermal analysis done for the exhaust manifold by cast iron, stainless steel, silicon nitride& zinc oxide. In this thesis the CFD analysis to determine the heat transfer rate, mass flow rate, pressure drop and thermal analysis to determine the temperature distribution, heat flux with different materials. 3D modeled in parametric software Pro-Engineer and analysis done in ANSYS.

Keywords: Exhaust Manifold, IC Engine, CFD Modeling for Exhaust Manifold.
