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). As real industrial problems are often characterized by high computational effort, the need for a CFD-DEM solver able to run on large clusters is obvious. To take a first step into this direction, the authors developed a coupled solver joining the two software packages LIGGGHTS and OpenFOAM®. While the former covers the DEM modelling, the latter describes the fluid dynamics of the continuous phase. The implementation of the code permits fully parallel simulations on distributed memory machines using MPI functionality. In a test case the correct prediction of pressure drop and minimum fluidization velocity is shown.
