Original Kurzfassung:
We report on the synthesis of the Discrete Element Method (DEM) modelling
the behaviour of granular materials and a finite volume model for the
continuous interstitial fluid using Computational Fluid Dynamics (CFD). DEM
captures the physics of granular materials best but is computationally
time-consuming. For this reason, the DEM is complemented by a Discrete Phase
Model (DPM) for disperse granular flow in order to accelerate the overall
simulation. In our case, both DEM and DPM are applied within one simulation
by using spatial domain decomposition. The implementation of the code
permits fully parallel simulations for all three models. We demonstrate the
efficiency and validity of our approach by three validation examples and
discuss the scalability of the coupling approach.
