Numerical investigation of particle mixing (Id 419)

Fine-grained solid particles from various industrial sources, which would otherwise be discarded, should ideally be processed to valuable products or inert residues. They contain valuable residuals, such as metals, that can be returned to the industrial cycle instead of being landfilled. This is one aim of the Helmholtz project FINEST in which this work is embedded.
The different finest powders need to be mixed and agglomerated for further processing. Our work in the project deals with the granular mixing. One aim is to describe particle flow based on the rheology of the bulk good while describing the mixing process among the particles using a transport equation.
The mixing process among particles is described by the transport equation. It needs to be coupled with the flow field of the particle bulk. The latter can be modelled by CFD, using e.g. FEM. Here, a rheologic model is required.
We are looking for someone with experience in CFD or other modelling to continue the implementation of this model.
