Problem Definition :Cavitation in Francis Turbine

I want to define cavitation in francis turbine. I am using the Rayleigh Plesset method, but am not aware of what value to feed for Saturation Pressure. I would like to know what CFX understands with Saturation Pressure & what should be its value.
Regards, Amit Roghs |

Tutorial 19 - Cavitation around a hydrofoil: Under "Preparing a simulation with cavitation" - "Adding cavitation."
Saturation pressure for Water/Water Vapor @ 25 C = 3574 Pa That's all the info I have. Best of luck, -Alex |

Dear Alex, Thanks for the response, but how to reduce the value pressure at outlet, due to which cavitation incepts. I am still not understanding what saturation pressure means? Is it the pressure at which water vapour oozes out of water?
Regards, Amit |
