Abstract: The task of thoroughly understanding fluid flows laden with solid particles poses a special problem within the field of investigating multiphase flows. Whenever highly detailed information concerning individual particle behavior is required, such settings are usually viewed in the light of a Eulerian-LaGrangian perspective. Demonstrating an example for a method used to describe LaGrangian particle motion within a Eulerian fluid in an exceptionally high level of detail, this chapter introduces a Six Degrees of Freedom (DOF), large LaGrangian particle model for (non-) spherical dirt particle motion and deposition within highly viscous fluids and solid fibre structures. The whole demonstration is based on the application example of dirt particle filtration processes in oil lubrication circuits of the automotive industry. In order to properly model this specific set-up a coupling between fluid, particles and solid fibre structures is required. Particles need to interact with the fibre structure, among each other and with the fluid such that larger accumulations of particles can actually form a realistic filter cake increasing the filter's pressure drop as well as its filtration efficiency. Moreover the non-spherical nature of real-life dirt particles is an issue. Thus the simulated particles are ellipsoids featuring pressure-/velocity probes across their respective surfaces, which also serve to detect particle-fibre as well as particle-particle impacts.
