A careful study of the effect of shape variation on inflow characteristics and the role of mullite coating on the thermal stability of exhaust manifold is the main aim of the present research article. The circular and semi-circular cross-section of the exhaust manifold are utilized in the present inquiry. An internal coating thickness of 1 mm has been used on the exhaust manifold. The prediction of natural frequencies and the variation of stress and deformation with frequency have been presented through modal analysis and simple harmonic analysis. The entire work has been carried out in the computational domain with the usage of ANSYS 19.2 general-purpose software to obtain the augmented results. The creation of mullite coating has resulted in the comprehensive decrement of heat flux of around 41.06% in the circular manifold and 34.84% in the semi-circular manifold. The noteworthy deformation reduction is also noticed with the application of mullite coating. Substantial thermal stability of semi-circular exhaust manifold is the final outcome of the present research study.
