In this study, using the lattice Boltzmann method, we simulate soot accumulation in porous media to examine the particle trap in a diesel particulate filter (DPF). The porous media are numerically formed for different inner structure with given porosity. The porous structure similar to the real...

Although diesel engines have an advantage of low fuel consumption in comparison with gasoline engines, several problems must be solved. One of the major concerns is that diesel exhaust gas has more particle matters (PM) including soot, which are suspected to be linked to human carcinogen. As one...
