| Abstract: | A numerical model of image force trapping particles is established for stainless steel filter by using the concept of two-phase flow.The diesel particulate flow field and image field and distribution of particulate concentration are simulated.The factors affecting the image force trapping efficiency are analyzed and calculated.The research results provide the scientific basis for the application of electrostatic trapping technology in controlling the diesel particulate emission. |
