Dear experts,
I often use MFiX as TFM model, and accustomed to simulate fluidized bed, and get desirable pressure drop.
However, I am in trouble in obtainning inhomogeneous solid volume fraction distribution along height direction, which is observed in experimental setup.
(Usually, my setting,or tutorial, gives roughly uniform distribution)
If you know any important parameters which affect solid volume fraction distribution,
I would appreciate it if you could tell me.
(e.g. drag model, solid viscous stress model, solid frictional stress model, and so on)
Kind regards
