Hi Everyone,
I am comparing an experimental study with CFD.During experiment they achived a choking flow condition for an Incompressible flow (Water).

1)Using the similar boundary conditions i am doing a CFD analysis but i cant get the choking conditions my mass flow rates are varrying by changing the down stream pressure.

Please find the atttachment for more details.(Boundar conditons etc...)

Kindly guide me how to ensure the choking condition for an Incompressible fluid using CFD.
