Fluidized Bed Simulation Coupling EDEM with ANSY

In this video, we present an application of the EDEM-Fluent coupling to a fluidized-bed simulation. The Fluent component was modelled using a two-phase Eulerian approach, using the DDPM model for the EDEM particle phase, allowing for the calculation of the pressure drop across particle bed and capture of the ensuing fluidized behavior.
