Hello everyone,

I would like to study a Prandlt-Glaubert singularity on a jet fighter.

I have a problem with my solution since I don't visualize any liquid water. Furthermore the pressure, the velocity and the density are constant in all my enclosure box.(the liquid generation rate is not constant but the fraction liquid is constant.)

Here are my settings :
density based
multi phase => Wet steam (I have no choice since density based). How can I choose the humidity percentage of the air inside the enclosure ?

Turbulent => K-epsilon

Operating condition : P=100965 Pa

Pressure inlet :
Total gauge pressure= 100965 Pa
Supersonic= 6300 Pa
=> v=330m/s

Pressure Outlet :
Total gauge pressure= 100965 Pa

I think that my issue is due to the Wet Steam option because I did not set a humidity rate.

Can I use an invicid model instead of a turbulent model for this case?

Also I would have liked to see simulate this singularity with a transient simulation and a pressure fonction depending on time in order to simulate an acceleration of the plane from Mach=0.7 to Mach=1.2 for example. Should I use a user define fonction ?

Thank you very much in advance for your answer.
