Advantages of coupling Passage®: Discrete Element Modeling (DEM) and CFD FLOW Software

By coupling PASSAGE®: DEM and FLOW software a variety of problems can be solved which can not be treated by using either one model individually. This capability allows modeling of liquids, gases, solid particles and their mixtures for many industrial problems in both micro and macro scales. It can be applied to process modeling of mixing, wetting, coating, filtration, fermentation and filling operations for applications in food, pharmaceutical, chemical, metals, plastics, glass, ceramics, powders processing and emission control.

DEM and FLOW modules can be coupled in a variety of ways depending on the application:

Many mixtures or two-phase flows require modeling of microscopic behavior of the material (e.g. air flow around solid particles. In this case DEM and FLOW modules are executed in parallel.
Industrial applications of particle flows usually involve billions of particles which cannot be efficiently modeled by DEM models. On the other hand, flow codes can not predict the material properties of mixtures or particle flows in sufficient detail due to the lack of accurate material models. In this case, DEM model is used to determine material properties for the FLOW model.
