-Numerical Study of the Effect of Soot Loading Condition on Soot Cake Layer-

Abstract

The numerical analytic model that could be expressed the effect of the soot loading condition were developed and validated with experimental data. Firstly, the permeability of soot cake layer was expressed with the function of the total porosity in soot cake layer. Secondly, the total porosity in soot cake layer was expressed with the function of the aggregation diameter of soot secondary particle.
