Application of Digital Material Methods to Silicon Carbide Diesel Particulate Filters

摘要

In previous work an advanced micro-scale simulation framework for DPF materials has been presented. This development comes as DPF developers continue to seek competitive advantage at the material level and the availability of computing power is improving to the point that micro-scale simulation may be considered for routine application for DPF materials optimization. The aim of the present work is to show an in-depth application of advanced micro-scale simulation methods to silicon carbide DPF materials currently in widespread use. The quality and utility of these simulations, targeting filtration and soot oxidation phenomena in SiC DPF material, is evaluated and the potential for the use of such advanced simulation technology is assessed in a materials development context.
