In filtration processes it is necessary to consider both, the interaction of the fluid with the solid parts as well as the effect of particles carried in the fluid and accumulated on the solid. While part 1 of this paper deals with the modelling of fluid structure interaction effects, the accumulation of dirt particles will be addressed in this paper. A closer look is taken on the implementation of a spherical, LAGRANGIAN particle model suitable for small and large particles. As dirt accumulates in the fluid stream, it interacts with the surrounding filter fibre structure and over time causes modifications of the filter characteristics. The calculation of particle force interaction effects is necessary for an adequate simulation of this situation. A detailed discrete Phase Lagrange Model was developed to take into account the two-way coupling of the fluid and accumulated particles. The simulation of large particles and the fluid-structure interaction is realised in a single finite volume flow solver on the basis of the OpenSource software OpenFoam.
