Ventilated Cavity simulation with natural cavitation

sarodesr · November 5, 2013, 04:59

Hi There, I am trying to simulate ventilated cavitation along with natural cavitation in Fluent V14.
I am using air as a non condensible, incompressible gas
Equation to be solved are-

1) Flow equations
2) Turbulence Equations
3) Volume Fraction for Vapor (cavitation model)
4) Volume fraction for Gas

Can I solve these equation using 3-phase mixture model (with cavitation model) or Do I need an extra UDF to solve gas volume fraction equation.

Hi,
it is possible to simulate a third phase in a multiphase cavitation system, with some limitations, see at the bottom of the page:
