Numerical Investigation of Particle Mixing (Id 451)

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 the process using flow simulations in OpenFOAM.
The particle flow is described based on the rheology of the bulk material, while the mixing process between the particles is described using a transport equation. In addition, there are terms for the segregation that takes place in parallel.
We are looking for someone with experience in CFD or other modelling to refine the implementation of this model and then perform parameter studies and validation using experimental data.
