Super sonic CD nozzle in fluent 16.1
 

Hello Everyone.

I am a beginner in Ansys , trying to design a classic case of 2D Supersonic CD nozzle with exit mach number 3.0 with an ambient pressure at exit .
But flow decelerates after throat.
I think my definition of BC are incorrect (I applied massflow at inlet , walls and pressure oulet BC).

If you have any suggest please share.
or if you know of any similar model to take reference from please share.

Since i believe this is a very generic case , should be easy to model .but still i am not able to model it.
Please help.

Regards
Mehlam

i think you can modify your out BC
