Stringent emission regulations around the world necessitate the use of highefficiency catalytic converters in vehicle exhaust systems. Therefore, determining the optimum geometry of the honeycomb monolith structure is necessary. This structure requires a high surface area for treating gases while maintaining a low pressure drop in the engine. In this book, an adapted subgrid scale modeling is used to predict the pressure loss of square and hexagonalcellshaped honeycomb monoliths. This subgrid scale modeling represents the actual variations in the pressure drop between the inlet and outlet for various combinations of wall thickness and cell density. A comparison is made between the experimental and numerical results established in literature. The present approach is found to provide better and more comprehensive results than the single channel technique.
