Pressure drop through centrifugal compressor

Hi all,
I'm trying to model an existing compressor which has a total pressure ratio of 1.8 and a mass flow of 0.7kg/s at 41000rpm. Essentially I keep getting pressure drops through the passage. Im running my mass flow as 'per machine'. I've read that a good BC template to set is Pressure inlet (set at 0 as Pref is atmospheric) and mass flow outlet. My hub and shroud are no slip wall and counter rotating wall respectively. Any thoughts? Brett |
