Default Centrifugal pump boundary conditions

Hi, I'm trying to simulate a centrifugal pump with 0.5m3/s, 2600RPM, and 15bar pressure rise.My boundary conditions are: Inlet:mass flow inlet, Outlet: 15bar static pressure. But I'm not getting the right pressure at the inlet which is supposed to be 1bar instead of same pressure as outlet. Am I putting the right boundary condition at the outlet or inlet? The fluid is water.

Thanks for any help

Hi Raghu my inlet mass flowrate is 500kg/s or 0.5m3/s. I saw a centrifugal blower tutorial in Fluent tutorial manual but not the pump. May I know which manual pls?

Thanks

Is this MRF or sliding mesh. Have you setup the rotating fluid zone correctly?

I'm using MRF. My rotating fluid zone is correct. But should I set the outlet boundary to be 15bar or 1atm pressure for the design pressure rise of 15bar?

Thanks

hi,
I'm new to this forum.


I'm also doing MRF.. I manage to run and re-model it in 2-D..
I'm trying to convert the MRF tutorial into 3-D for my centrifugal pump project..
Would some one advise me the best way to do it..

Thnaks
