B141 ミクロ多孔質における微粒子輸送・堆積のLBM解析(OS-4:マイクロ・ナノ熱工学(II))
詳細
In this article, we discuss microscopic behavior of the particle in micro porous media such as Diesel Particulate Filter (DPF). We developed a numerical simulation technique on particle transport and deposition using a Lattice Boltzmann Method, that was applied to the DPF structures obtained by micro-focus X-ray Computed Tomography. The LBM simulation on a small DPF domain showed a pressure drop curve related to the transition of filtration phenomena. We also conducted the LBM simulation on a large DPF domain. Particle deposition was identified in the middle of porous domain, resulting in variation of stream line due to particle loading.
