C5 will derive new models for an improved momentum coupling, considering the anisotropic nature of the morphology of the particle assembly, for DEM/CFD. The motivation for the project is that currently only strongly simplified models are used for the description of gas phase flow field in large-scale DEM/CFD simulations. The exact geometry of the individual particles is not taken into account in the description of the gas phase, instead the granular phase is represented just by the assumption of a spatially distributed, but isotropic, porosity. This deficiency will be ultimately eliminated by C5. For this purpose, the gas volume fraction (local porosity) in the gas-particle interaction terms will be replaced by a second order tensor to account for the anisotropy of the gas volume fraction and its gradient in each spatial direction.
