- Microscopic Observation and a Numerical Approach on Flow and Particle Deposition Behaviors in a Diesel Particulate Filter
抄録
In this article, we discuss microscopic particle deposition behaviors in a Diesel Particulate Filter (DPF). We measured a particle deposition process in a porous side wall in the DPF by using a long range microscope connected to a CCD camera. We also monitored variation of pressure drop due to particle deposition. We confirmed that the pressure drop curve had two different modes, i.e., a rapid increase of pressure drop observed in the initial stage and a moderate increase in the later. The microscopic observations show that in the initial stage, particles are trapped inside the porous wall and that thereafter particles accumulates on its surface of the porous wall. We also conducted a lattice Boltzmann Simulation of a particle depositon process in a porous system.
