Abstract
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 is suspected to be linked to human carcinogen. As one of the key technologies, a diesel particle filter (DPF) has been developed to reduce particle matters (PM). Since it is difficult to examine the local flow or temperature field in porous media experimentally, we try to simulate combustion flow. Two-phase Automaton is applied to produce the porous structure based on these particle behaviors. The porosity and tortuosity are freely changed by the profiles of the two-phase interface. Combustion field is simulated in this porous media flow, assuming that soot is attached to the wall surface. Results show that the soot is burned through the reaction with oxygen, similar to the regeneration process of DPF.
