abstract = {<p style="text-align: justify;">A diesel particulate filter (DPF) is a key technology to meet future emission standards of particulate matters (PM), mainly soot. It is generally consists of a
wall-flow type filter positioned in the exhaust stream of a diesel vehicle. It is difficult
to simulate the thermal flow in DPF, because we need to consider the soot deposition and combustion in the complex geometry of filter wall. In our previous study,
we proposed an approach for the conjugate simulation of gas-solid flow. That is, the
gas phase was simulated by the lattice Boltzmann method (LBM), coupled with the
equation of heat conduction inside the solid filter substrate. However, its numerical
procedure was slightly complex. In this study, to reduce numerical costs, we have
tested a new boundary condition with chemical equilibrium in soot combustion at the
surface of filter substrate. Based on the soot oxidation rate with catalysts evaluated
in experiments, the lattice Boltzmann simulation of soot combustion in the catalyzed
DPF is firstly presented to consider the process in the after-treatment of diesel exhaust
gas. The heat and mass transfer is shown to discuss the effect of catalysts.</p>},
