【Abstract】 In this paper, a 2D numerical model has been applied to simulate the collection efficiency and pressure drop of the clean honeycomb wall-flow ceramic monolith filter, combined with the filtration theory. The result indicates that the mathematic model has satisfactory accuracy, at the same time, the simulation result can be used as a reliable tool for optimized design of diesel particular filters.更多还原
