Models, algorithms and validation for opensource DEM and CFD-DEM

Abstract: We present a multi-purpose CFD-DEM framework to simulate coupled fluid-granular systems. The motion of the particles is resolved by means of the Discrete Element Method (DEM), and the Computational Fluid Dynamics (CFD) method is used to calculate the interstitial fluid flow. We first give a short overview over the DEM and CFD-DEM codes and implementations, followed by elaborating on the numerical schemes and implementation of the CFD-DEM coupling approach, which comprises two fundamentally different approaches… Show more

“…In this paper the simulation rests on the Discrete Element Method code ''LIGGGHTS'' initially employed by Kloss et al [15,16]. The code is enhanced edition of the granular package of classical MD simulator LAMMPS [17] and is executed in a new Hertz-Mindlin granular contact model.…”
