To reduce diesel particles, a diesel particulate filter (DPF) has been developed for the after-treatment of exhaust gas. Since the filter would be plugged with particles to cause an increase of filter back-pressure, filter regeneration process is needed. In this study, we simulate the flow in DPF by the lattice Boltzmann method (LBM). Here, the real filter is used in the simulation. The inner structure of the filter sample is scanned by a 3D X-ray CT technique. Especially, to consider the heat transfer to the solid wall of the filter, the equation of heat conduction was solved, simultaneously. That is, the approach for the simulation of gas-solid flow was presented.

为了减少柴油微粒，研制了柴油机微粒过滤器（DPF）用于尾气后处理。由于过滤器会被颗粒堵塞，导致过滤器背压增加，因此需要进行过滤器再生过程。本文采用晶格玻尔兹曼方法（LBM）模拟了DPF内的流动。这里，仿真中使用的是真实滤波器。通过三维x射线CT技术扫描过滤器样品的内部结构。特别考虑了对过滤器固体壁的传热，同时求解了热传导方程。即提出了气固流动的模拟方法。
