Hello.

I have very important question.

I have to simulate a spillway with aerator device, in open foam.(for prevention of cavitation)
Can open foam simulate this chute with artificial injection air into the ramp?
or the ramp (eg. offset,groove or ...) is
Sufficient for prevention of cavitation?(without injection air into the ramp)
see this pic

Yes, using interFoam, but it depends if it includes the treatment of fine bubbles (smaller than the mesh size).

Regards.

thanks santiagomarquezd.
but can flow 3d do that? because i don't have any experience in openfoam.

Well, I think you should ask in a Flow 3D forum, I don't know much about this software but I think it is capable to do so except for the part of the fine bubbles. I have a solver to manage this kind of problems with two scales of interfaces but in OpenFOAM (without cavitation).

Regards.

i asked this question in flow3d forum but nobody can't help me.
can fluent do that simulation?

Yes, with the VOF solver, but with the same limitations of FLOW3D.

Regards.

Hi. The limitation of VOF is the treatment of the fine bubbles (smaller that the mesh size).

Regards.
