抄録(英) | TWC Membrane fabrication, soot trapping on GPF, and soot trapping on TWC membrane have been studied using computer numerical simulation. The results of pressure drop, filtration efficiency, and morphology visualization were satisfied the experimental results. The simulation clarified the trapping phenomena up to the 3D-nanoscale resolution, which overcame an experimental limitation. Visualization revealed the particles first trapped on the substrate generating a dendrite structure at the constricted area. It expanded by accumulating flying particles until the bridge structure was completed, which is the same point of 100% filtration efficiency. 翻訳 |
