Abstract

Stringent emission regulations around the world necessitate high efficiency catalytic converter to be used in vehicles exhaust system. It is essential to determine optimum geometry of honeycomb monolith structure which required high surface area to treat the gases while maintaining low pressure drop to the engine. In this paper, adapted sub-grid scale modeling is used to predict the pressure loss of square cell shape of honeycomb monolith structure in catalytic converter application. This sub-grid scale modeling represents the actual variations of pressure drop between the inlet and outlet for various combinations of wall thickness and cell density. Comparison is made to the experimental and numerical work established in the literature. This approach is found to give better and more comprehensive results over the single channel technique
