Hydraulic jump assessment

kimyd

Dear friends,

I am interested to model about the fenomenon Hydraulic Jump producing by airflow over a mountain ridge (1 Km heigth) to simulate using CFX-11. I would like to know some boundary conditon, especially in the inflow boundary. So far I did to set the inflow velocity using powerlaw, but no result show the hydraulic jump phenomena.

Any suggestion will be apreciate

Thank You very much.
