CFD simulation of particle flow dynamics in a two-dimensional spouted bed

In the present study, the CFD simulation based on, an Eulerian–Eulerian two-fluid model was employed to predict the flow behavior of spouted beds. Gidaspowsʹ drag model and Lunʹs granular kinetic theory were adopted to describe the interfacial forces and the solid stress, respectively. The commercial fluid dynamics code FLUENT version 6.3.26 was chosen to solve the model equations. The simulated velocity profiles were compared with results obtained by Liu et al. (with a cylindrical spouted bed and glass sphere). The simulated results showed good agreement with the experimental data.
