This paper presents a computational investigation of the effect of space velocity on the dynamic performance of an automotive catalytic converter. The objective is to develop a better fundamental understanding of the converter's performance under actual driving conditions. The study employs a single-channel based, one-dimensional, non-adiabatic model. The transient effects are considered by modulating the air-fuel ratio and compositions of the exhaust gases entering the catalyst. The results elucidate the role of space velocity in determining the catalyst behavior under transient conditions. At high space velocities, the catalyst performance is relatively more influenced by imposed transients.
