Dear friends,

I am trying to simulate gas+solid two phase flow using Eulerian model with kinetic theory of granular particle aproach.

I require to apply wall boundary condition for solid velocities and granular temp. Now, from the literature and from the FLUENT manual as well, people use Johnson and Jackson boundary condition for solid phase shear and granular temp at wall.

Now, my question is how to enable solid phase boundary condition at walls for solid shear stress? Is that if i have selected specularity coefficient and input some value for that in wall-momentum boundary condition panel, then i have activated Johnson and Jackson boundary condition? If not, how to implement such boundary values using Johnson and Jackson condition?

Please help me. Thank you very much for your time in advance. If you need more information before you can answer my question, please advise me.

Regards, -US
