The Discrete Element Method (DEM) coupled to Computational Fluid Dynamics (CFD) is used to predict dense fluid-particle system in a blind study using the in-house code GenIDLEST (Generalized Incompressible Direct and Large Eddy Simulation of Turbulence). The experimental measurements were performed at the Department of Energy’s (DOE’s) National Energy Technology Laboratory (NETL) at three different superficial velocities in a 0.076m×0.23m×1.22m bubbling fluidized bed with 3.26 mm Nylon beads. Experimental measurements include the mean and rms of pressure drop between specific locations, the first four moments of solid velocity components, and time series of pressure drop at selected locations in the bed. The predictions capture the trends in the change in bed hydrodynamics with an increase in the superficial velocity. While good qualitative agreement is found with experiments, quantitative agreement is fair. Factors that might cause deviations in predictions are discussed.
