Experimental and Numerical Assessment of a Multi-Cylinder Engine Exhaust Manifold

Abstract

Abstract This research presents an experimental and numerical analysis to examine the thermal loading of the exhaust manifold of a multi-cylinder gasoline engine operating under steady-state conditions. The local skin temperatures and surface heat fluxes variation are focused throughout the external surface of the exhaust manifold. A 3D modeling and simulation are employed in the numerical analysis using Solidworks software for modeling and ANSYS software for simulation. The generated numerical results are in good agreement with the measured exit gas temperatures and skin temperatures experimentally.
