Two approaches are commonly used for modeling the vertical mixing of binary-mixture fluidized beds, Computational Fluid Dynamics (CFD) and macroscopic modeling. A common realization of the latter one is the Gibiralo–Rowe (G-R) model, which uses the

Eulerian–Eulerian modeling is widely applied in simulations of multi-phase flows in fluidized beds. However, the validity of this model is questionable, especially with the limitation of gas–solid drag closures. In this study, CFD simulations wer

In most cases, the stationary fluidized beds are composed of two different particle classes (inert and active particles), and the concentration profile of these binary beds along the vertical axis is crucial regarding the effectiveness of the reactor
