The insertion of an axially positioned non-porous and porous draft tube into the conventional spouted bed has shown potential advantages in stability and flexibility of the system and controlling particle trajectory history. In this work with computational fluid dynamics (CFD), important information on the flow field within three types of spouted bed has been provided and influences of using internal tube on spouted beds hydrodynamics were investigated. The simulation used the multi-fluid Eulerian-Eulerian approach based on kinetic theory of granular flows (KTGF), incorporating a kinetic-frictional constitutive model for dense assemblies of particulate solids and Gidaspow’s drag model for the interaction between gas and particles. Finally, the modeling results were compared with the experimental data from literature.
