Abstract: Progress in the modelling and simulation of flow processes in gas/particle systems carried out by the authors| research group are presented. Emphasis is given to Computational Fluid Dynamics (CFD) models that use multi-dimensional multi fluid techniques. Turbulence modelling strategies for gas/particle flows based on the kinetic theory for granular flows are given. Sub models for interfacial transfer processes and chemical kinetics modelling are presented. Examples are shown for several gas/particle systems, including flow in risers and reacting systems.

Keywords: computational fluid dynamics; CFD; multiphase flow; circulating fluidised beds; CFB; modelling; simulation; reactive gas solids; turbulence modelling; kinetic theory; granular flows; interfacial transfer; chemical kinetics.
