摘要

Along with the increasingly stringent emissions regulations, the Diesel Particulate Filter (DPF) is one of the leading technologies for reducing particulate matter in diesel exhaust. In this study, it is presented that the Carbonized Micro-Wood Fiber (CMWF) is used as filter material of DPF. Firstly, the permeability and the inertia coefficient are obtained by numerical simulation method, then the geometric relationship between the ∆p/H (the ratio of a pressure difference of the front and back of a filter body and the thickness) and the v_1 (exhaust flow velocity in front of the filter body), lastly, the test is performed utilizing the self-designed detachable DPF and the flow characteristics test bed. Theory and test proves that the numerical simulation method can be consistent with the test very well, which shows the DPF with bigger pore diameter and longer axial length should take priority over the others.
