Analytical Solution on Flow and Pressure Drop Model in DPF
In this paper, a 2-D model is developed to study the gas flow in a honeycomb structure ceramic diesel particulate filter(DPF). This model describes the steady state flow and pressure in in let and outlet channel. The analytical solution was derived from the conservation of mass and momentum equations. Applying the boundary conditions, the flow field was predicted depending on the pressure drop and the geometry as well as material properties of DPF. The parametric study indicated that the porous porosity, thickness, channel length and width are the main parameters controlling the DPF pressure drop. the analytical solution can be used as a reliable tool for optimized design of diesel particular filters.
