cavitation modeling and pressure distribution

arazgaldy

Dear all cfd members,

I modeled the three kinds of problem in cavitation mode in fluent:

1-2-D nozzele 2-2-D hydrofoil naca0015 3-3-D marine propeller

but in all of these three cases i encountered a problem that pressure distribution falls some blew vapor pressure . fore example if define the vapor pressure 3500 pascal, then when cavitation occure i get pressure about 2500 pascal in cavitation region.

in my opinion this can not be true.

is ther any body to help me about this problem.

regards,
