Soot Particle Deposition within Porous Structures using a Method-of-Moments-Lattice-Boltzmann Approach
SINOPSIS
This paper deals with the combination of two computational methods to simulate the flow of particle-laden fluids through porous structures: the lattice Boltzmann method (LBM), which is a method to solve the Navier-Stokes equation in complex geometries and the method of moments (MoM), which describes the time evolution of nonhomogeneous particle distributions. The combination of these methods makes it possible to take phenomena into account that depend on particle size and size distribution of the transported material. It is also possible to simulate changes in the size distribution. The applicability of the method is demonstrated by simulating the deposition of diesel soot on the porous structure of a filter. The geometry of the filter material has been reconstructed from CT scans of the filter material.
