Cavitation modelling in inducer!
 

Hi !

I have worked with cavitation model of fluent 6.2.16 in a blade cascade of the inducer (unsteady). I have very good results at Q = Qn and Q>Qn. But the problem is when I work whit Q<Qn. There is a very hard fluctuation for pressure at the inlet of domain.

Can someone help me?

Thank a lot Rafael

Help me!
 

I need basic information about inducer design methodology. Rafael helps me! doesn't? Just information.
