Multi-fluid CFD modelling of fluidised bed reactors

Abstract

Progress in modelling and simulation of flow processes in gas/particle systems carried out at the authors’ research group are presented. Particular emphasis is given to computational fluid dynamics (CFD) models that use the 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 the interfacial transfer processes and chemical kinetics modelling are presented. Examples are shown for several gas/particle systems including flow in risers, segregation by size and reacting systems.
