Need help for 3D-Nozzle cavitating flow!!!

I am using mixture model to modeling my object, which is 3D rectangular Nozzle.
The boundary conditions are:
-Inlet: pressure inlet (total pressure and static pressure)
-Outlet: static pressure
-Cavitation model: Schnerr and Sauer model
-Turbulent model: RNG k-epsilon with enhan wall function
Solution scheme: PISO unsteady
-pressure: second order
-vapor equation: QUICK
-Other equation: second order upwind
But the results seem different with experiment result and when I check average static pressure at Inlet, the value is equal the setting total pressure.
I dont know why had this results.
Is this solution method and orther option I chose correct and any suggestion for my problem?
Thank you very much!
