	  abstract     = {In the current work, a numerical parametric study was
performed in order to model the fluid mechanics in the riser of a
bubbling fluidized bed (BFB). The gas-solid flow was simulated by
mean of a multi-fluid Eulerian model incorporating the kinetic theory
for solid particles. The bubbling fluidized bed was simulated two
dimensionally by mean of a Computational Fluid Dynamic (CFD)
commercial software package, Fluent. The effects of using different
inter-phase drag function (the drag model of Gidaspow, Syamlal and
O-Brien and the EMMS drag model) on the model predictions were
evaluated and compared. The results showed that the drag models of
Gidaspow and Syamlal and O-Brien overestimated the drag force for
the FCC particles and predicted a greater bed expansion in
comparison to the EMMS drag model.},
