Optimization of DPF Structures with a 3D-Unit Cell Model
Publié en 2013
The 3D unit cell model approach offers an efficient tool to analyze the influences of geometrical design (channel shape and arrangement, filter length, wall thickness) and filter material properties (permeability, soot loading characteristics) on the performance of ceramic particle filter structure in the soot loading process, assessed by pressure loss and soot loading capacity. It does correctly predict the corresponding relations and trends as could be proved from an experimental evaluation. An application of the model as a virtual tool for efficient optimization of a filter structure towards user target values for an specific application could help to avoid expensive practical trial and error loops with costly adaptions of real tools.
