Augmenting Coupled DEM Simulations by Efficient Particulate Models for Dilute Granular Flow

Description

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 simulation. Both DEM and DPM are applied within one simulation by using spatial domain decomposition. The implementation of our In-House code permits fully parallel simulations for all models. We demonstrate the efficiency and validity of our approach by validation examples and discuss the scalability of the approach.
