Static and Total Pressure Analysis of Three Way Catalytic Convertor Using CFD

Air pollution from automobiles both commercial and passenger vehicles push the research to make changes in catalytic convertor. Most of the commercial vehicles like coal transport and mineral transport trucks relay on diesel fuel in this regard, we consider the effects carbon monoxide, hydrocarbons that have not been burned, and nitrogen oxides. As a result of incomplete combustion, alcohols, aldehydes, and other partial oxidation products are released into the air. The whole process of this project is done with the help of CFD approach because it will reduce the material waste and we can optimize according to our desired results. In this study, a numerical analysis has been carried out on the catalytic converter by varying the coating materials. Magnesium Oxide (MgO) and Platinum with Palladium was selected as coating materials. For comparison purpose, normal catalytic converter without coating was analysed using CFD software. Different output characteristics of the exhaust gases’ static pressure and total pressure in the catalytic convertor are compared with each other. Outcomes of the numerical analysis shows that the catalytic converter which is coated with Platinum and Palladium particles yields the better static and total pressure than that of normal and magnesium oxide (MgO) particles coated catalytic converter.
