Nozzle modelisation: Boundary conditions
1 Attachment(s)
Hi Foamers,

I want to simulate a flow in a nozzle wich can be subsonic or supersonic. I have defined a nozzle thanks to blockMesh, I use sonicFoam and now I have some difficulties to choose the boundary condition's.
Currently I have:

p : totalPressure
U: pressureInletVelocity (value uniform(0 0 0) )
T: totalTemperature

p: waveTransmissive
U: zeroGradient
T: zeroGradient

You can see my 0 file if you want more informations

Thank you for all recommandations ;)

Please I need some help :(

My simulation doesn't give me good results so I would like to know if the boundary conditions are ok or not.

Thank you :)

Ok my conditions seem to be good as the simulation looks fine :)

Hi Valentin,
I am new in openFoam and I am trying to simulate a nozzle flow as well. I would like to ask you if you have changed or kept your boundary conditions of your first message in this forum. Please help me, thank you in advance.
