Thanks Srr, for sharing titles. Well, as your bed is moving slowly (like entrained flow gasifier), it does affect by turbulence. Generally, with dense phase, we can assume flow is laminar. Anyway,...

Well, i didn't applied turbulent model with assumption that laminar gas-solid flow in dense particles where inertia of the solid particles is much more higher than the gas and role of the gas phase...

Srr, one thing i am not sure, why did you used turbulence model?? as a packed bed simulation where presence of dense particle phase usually there is no need to implement turbulence model

antonio,

yes, you can solve your problem with Fluent 12.

if you wish to use Euler-Granular model to simulate gas-solid packed bed you need to write UDF for heterogeneous reactions.

With...

and what kind of UDf are using for heterogeneous reactions??
