| Summary: | A Lagrangian solver to realistically model large, non-spherical dirt particlesand their behaviour in the vicinity of deformable filtration fibres has beenprogrammed. While this paper focuses on basic solver concepts as well asdrag force implementations, a related article, concerning the realisation ofinteraction effects and result verification, is forthcoming, [3].Within the framework of a digitally reconstructed, deformable filter fibregeometry, the solver traces the governing multi physics effects down to theoccurrence of single force- and torque vectors. In order to go from an initial,spherical particle model [2], to a more sophisticated, non-spherical model,the capabilities of a Six Degrees of Freedom Solver have been included inthe programming. A panel model and the concept of satellite help points areused to handle particles that encompass several fluid calculation cells.An innovative drag force implementation allows the consideration ofrotational- and shear flow effects on particle motion. Results are evaluatedand compared to an analytical formulation. |
