Where is the "KTGF" model?? CFB simulation
 
Dear all,
I see many persons when they simulate the CFB, they use KTGF model to simulate the solid phase.
Does that mean just active the "granular" button and specify some phase property?
at this case ,how to specify the viscosity for solid in the material panel??
in E-E model the solid was considered as fluid as we know.

thankssssss!!!!!!

hi. like you said you just activate the "granular" button in the secondary phase panel.
for the second question(how to specify the viscosity for solid in the material panel) you don't need to specify the viscosity of solid. enter any value (viscosity of air or viscosity of water for example). because i "think" for this model fluent don't take solid viscosity into account.

That's correct (ANSYS FLUENT User's Guide 13, page 1224, point 5) :)
