A finite-volume-based two-dimensional wall-flow diesel particulate filter regeneration model

A methodology for estimating the permeability of a soot deposit in a wall-flow diesel particulate filter

“…the CFD method with the Navier-Stokes equations), there is a fundamentally weak point regarding their accuracy. Although realistic implementation of the microstructural properties of a particulate deposit have a large influence on the accuracy of the DPF model, the important properties such as the permeability and the porosity of a particulate deposit are commonly assumed to be constant or are derived from simplified algebraic relationships, [20][21][22][23][24][25] where the shape of the soot particles is assumed to be spherical despite the facts that the morphology and the microstructure of soot deposited in actual DPFs have a variety of forms. [26][27][28][29][30] The main objective of this study is to present a model-based technique which is easy to apply to realworld DPF design and development processes.…”

Development of a 1-D Catalyzed Diesel Particulate Filter Model for Simulation of the Performance and the Oxidation of Particulate Matter and Nitrogen Oxides Using Passive Oxidation and Active Regeneration Engine Experimental Data

“…Other research works of interest about CPF models are the publications of 3D modeling of diesel particulate filters by [22,23], 3-D models [24,25] another 2D catalyzed filter regeneration model by Frey et al in 2007 [26], the use of a 3D model (Axitrap -commercial DPF simulation software by Exothermia [27]) for the optimization of catalyst zoning in diesel particulate filters in 2008 by Koltsakis et al [28] and also presented at the 6th International CTI exhaust forum in Nurtingen, Germany in 2008 [29]. Finite volume-based approaches have also been successfully implemented to study the flow processes inside a diesel particulate filter, such as those published in [30] and [31].…”
