Modelling of Catalytic Converter in CNGV Cold-start Engine

Modelling of cold-start engine behaviour at catalytic converter is a difficult task as it involves complicated convection-diffusion-reactions flow.This work presents a CFD calculation to predict the transient thermal and conversion characteristics of catalytic converter during the light-off operatio...
