• In this work the Computational Fluid Dynamics modeling of the Automotive Catalytic Converter is comprehensively performed, including the study of the Flow Field distribution and the Temperature distribution under cold, non-reacting flow for six different monolith properties. A sensitivity study of some key lengths values was also performed. Later, the effect of the reactions is included by using an example reaction of Ammonia oxidation, which by the use of the multi-scale lookup tables technique allows to model the sub-grid effects of diffusion into the washcoat, that otherwise would be impossible to consider properly with alternatives modeling approaches.
