Spouted bed - Jet penetration / bubbling

I am modelling a (spouted bed using a euler-euler granular model in Fluent 14.
Even though I am following the model choice of some paper which can reproduce quite well the experimental data, I cannot obtain a correct jet regime.
The authors of the experimental work state that the spouting regime starts around gas inlet velocity of 38 m/s, but in my simulation I cannot get any spouting.
Using around 41 m/s, the gas barely penetrates the solid bed. Using 55 m/s, a bubbling regime happens.
Any thoughts on it??

i have a same problem,i want to modeling hydrodynamic of spouted bed my experimental reference is HE et al .
diameter of inlet=19mm
diameter of solid=1.41 mm
inlet velocity=41 m/s
initial volume fraction of solid=0.588
drag model= Gidaspow
other Authors reach spouting, in my simulation I cannot get any spouting.
did you solve your problem?
can you help me?
thank you in advance
