How to Use Porous jump BC???
 
I want to simulate the turbulent flow in a channel, whose bed is porous and there is upward seepage through the bed along with a turbulent flow in the channel.

Is it possible to simulate the laminar flow in the porous sand bed and turbulent flow above the bed at the interface simultaneuosly to get velocity and shear stress distributions? How to set the boundary condition at the sand & water interface which will take into account the roughness of sand and the upward seepage velocity?

I am thinking to use Porous JUMP Condition But FLUENT mannual does not provide sufficient information to use it. CAN ANYBODY plEASE HELP ME ON THIS...

Please help at the earliest. Thanks in advance.
