HI all,

I am doing cavitation in Nozzle in STAR-CCM+. Actually i mentioned the reference pressure (101325 Pa) in reference values.

At inlet i have to give 100 bar Pressure and outlet 80 bar pressure. I have specify the saturation pressure 3000 Pa .

Which value i have give in saturation pressure (Pref-Psat) or Psat because i specified the reference pressure and also inlet and outlet.

Please help me

Regards
venkat

sounds like you need to read the important help on settings pressures in star-ccm+ and you will then hopefully learn than in this case your reference pressure should probably be more like 80 or 100 bar

saturation pressure is a material property like density and so is in absolute pressure units
