Work­ing field:

The coupling of numerical flow simulation (CFD) and the discrete element method (DEM) with the aid of coarse graining methods to CFD-CGDEM is a new, efficient numerical method for simulating combined particle/fluid flows. Based on the DEM, a freely selectable number of particles is combined into a representative parcel. This reduces the number of particles to be tracked, which shortens the calculation time accordingly and makes the method interesting for the calculation of industry-relevant problems.
The task to be fulfilled in the context of CFD-CGDEM, which calculates the trajectories of parcels using scaled contact and fluid interaction models, is to compare existing scaling approaches and to investigate which of the approaches delivers accurate results with increasing scaling factors that have previously caused difficulties. With the help of an adaptive coarse graining approach which allows the use of different scaling factors in geometrically narrow and wide areas, the extent to which such a method enables the use of CFD-CGDEM also in technically important systems with geometrically thigt fixtures is to be investigated.
