Abstract

Numerical and experimental fluid dynamics analysis has been performed for the automotive catalytic converter under isothermal condition focusing on two primary problems of catalytic converters: (1) the low conversion efficiency; (2) high pressure drop. The K-ε turbulent model based on the eddy viscosity model combined with the fluid flow model in porous media was used as the physical governing equations. The numerical results agreed with the experimental data obtained by LDV and hot wire anemometer. Some insights and optimization design concepts obtained in the present work provide valuable information to the converter designer.
