000014085 520__ $$2eng$$aA two-fluid model based on the kinetic theory of granular flow, for the rapid-flow regime, and the Coulomb friction law, for the slow-plastic regime, is applied to predict the hydrodynamics of dense gas-particle flow in a large-scale three-dimensional fluidized bed. Two different models for the particle stress tensor, in the elastic-inertial regime, are examined to assess their ability to predict the dynamics of the bed. The numerical results are validated against published experimental data and demonstrate the significance of the stress tensor in the elastic-inertial regime. Different flow regimes are identified, in the context of fluidized beds, through the dimensionless Inertial number and the main characteristics of each regime are discussed to better understand the complex dynamics of fluidized beds.
