cavitation model

Dear Sir:

When I define pressure inlet and pressure outlet bondary conditions, after the solution was fully convergent; I turn on cavitation model. But the flow rate on inlet change with steps. I run 20000 steps, the flow rate on inlet still change with steps. Could you answer me this questions?

Thank you

Hy,

I also tried some time ago the cavitation-model and I had the same problem. In my opinion, modeling of cavitation (and getting good results) is not yet possible. Other cfd-codes do not yet have such a model or just try the first steps in that.
