Numerical simulation of moving and reacting bulk material passed by reacting gas flows (Illana/Scherer) develops a novel DEM/CFD framework, especially designed for the challenge of simulating reacting moving granular assemblies. In FP2, the focus will be on all aspects relevant to non-spherical and polydisperse particle assemblies. The polyhedron-based method in large-scale applications is most often required only locally, while the consideration of spheres is sufficient for the rest of the domain. Dynamically switching the particle topology from an unresolved (spheres) to a resolved (polytope) description as they pass an important region is the expected solution. For reactive solids, a cost-effective size- and shape-changing model based on the local reaction rate is necessary. Reactions can also lead to non-convex particle shapes and therefore require a method to compute the interactions of non-convex particles. The project will incorporate all of the models devised in the other projects in the DEM/CFD framework, released as open-source software during FP2.
