Hi everybody:

I'm running a FCC Riser gas-solid simulation, and I need to set the Johnson and Jackson BC for Tangential velocity of solids and Granular temperature at wall.

What I've done is to define at wall-surfase_body Boundary Conditions for the solid phase in Momentum/Shear Condition a value for Specularity Coefficient, and in Multiphase/Granular Conditions, selected the Johnson-Jackson option and defined a value for the Restitution Coefficient.

Doing this is the way to define the Johnson-Jackson BC?

I think that specifying the Specularity Coeff I defined the Tangential Velocity BC, but I'm not sure that defining the Restitution Coeff I'm defining the Granular temperature BC.

Any help is very welcome.

Regards,

Ignacio

I would like to know this too, I'm working with Eulerian granular flow and I found an article that the author used this approach.
