摘要

In an effort to better understand the underlying chemistry in three-way catalytic converters (TWC), several detailed micro-kinetic models have been developed in the literature [1]. Microkinetic models can capture the observed features at a wide range of operating conditions. They are especially useful under conditions of intrinsic reaction control. However, incorporating detailed microkinetic models, consisting of hundreds of reactions, in computational fluid dynamics simulations for TWC can be prohibitively computationally expensive.
