Modeling of An Exhaust Gas Three-Way Catalyzer for Its Thermo-Fluid Analysis

Abstract

As to three-way catalyzers (TWC) for automobile exhaust gas, further reduction of exhaust emissions in demanded, and therefore it is necessary to optimize the conversion characteristics, geometry and installation position of the catalyzer. For such a purpose, the authors are planning to carry out three-dimensional numerical simulation of heat, flow and gas composition in a TWC. As a first step in this study, the authors have created a detailed analytical model for thermo-fluid with chemical reaction in a TWC and carried out a fundamental examination.
