Abstract
As to three-way catalyzers (TWC) for automobile exhaust gas, further improvement in the purification performance of exhaust gas is required. Therefore it is necessary to optimize the purification characteristics and geometry of the catalyzer. In this study, the authors have created a detailed analytical model to analyze thermo-fluid with chemical reaction in a TWC and carried out three-dimensional numerical simulation of heat, flow and catalytic reaction in the TWC.
