Diesel engines have been used in a wide variety of commercial vehicles. However, several problems must be solved. One of the major concerns is that diesel exhaust gas has more particulate matters (PM) including soot, which are suspected to be linked to human carcinogen. Then, more strict diesel emissions standards are being set in many countries, and diesel particulate filters have been developed to reduce PM in the after-treatment of exhaust gas. In this study, we conduct Lattice Boltzmann simulation on combustion in metal honeycomb filter, where metal obstacles with square shape are inserted in 2-D duct flow with the porosity of 0.8. To examine the filter properties, we change the arrangement and size of metal obstacles in the filter. Results show that the combustion reaction is well simulated to discuss the burning rate of soot particles in the exhaust gas.
