Fundamental investigation of particle-layer rearrangement in ceramic wall flow filters by resolved particle simulations

Goal of this project is to investigate the main influencing factors, such as local flow conditions, filter and particle properties, for the rearrangement processes in wall flow filters. Furthermore, the project aims at determining the system sensitivity on the deposition topology employing Lattice Boltzmann fluid flow simulations. By accounting simulations with resolved particles, detailed investigations of rearrangement processes can be performed while allowing for an independent investigation of input parameters.
