Default FLuent CAvitation Model requires Turbulence?

Hello

Can fluent's mixture model be used without turbulence..if so ..please check the rate of evaporation and condensation rates where Characteristic velocity = sqrt(turbulent kinetic energy)..if TKE =0 (no turbulence considered) source terms are zero ?!

If I use laminar flow, how is the source computed?

Thanks

I guess you should consider turbulent flow...I don't remember seeing laminar flow with cavitation, yet.

Thanks for your reply MA

If I do cavitation with no turbulence..it still works ! i dont knw how they manage to get the evaporation and condensation working without the "k" in their equation sounds interesting..

Many of the works in cav actually use a lam assumption since the cavitation effective viscosity >> turbulent effects...so ..kinda neglected.

But, anyways, I was wondering about fluent's ability...now with lam i can see it works but ..jus cant find how !
