... representations and thus avoid the excessive computational resources required to track all the discrete sediment particles of the bed material in the domain of interest. In the current work a periodic domain is assumed making this type of simulation more feasible for CFD-DEM simulations. An augmented soft sphere...

... kinetic energy. Furthermore, the non-spherical DEM model is coupled with an in-house fluid flow solver (GenIDLEST). The combined CFD- DEM model results are validated by comparing to experimental measurements in a fluidized bed. The parallel scalability of the non-spherical DEM model is evaluated in terms...

...CFD DEM ANALYSIS OF A DRY POWDER INHALER ABSTRACT Dry powder inhalers (DPIs), used as a means for pulmonary drug delivery, typically contain a combination of active pharmaceutical ingredient (API) and significantly larger carrier particles. The micro-sized drug particles - which have a strong...
