I am using Fluent to simulate the flow with cavitation.
Firstly, I choose mixture and k-e model, phase-1 is water liquid, phase-2 is water vapor. Pressure of inlet is 202650Pa and outlet is 0Pa. Caculating it until the convergence.
Secondly, add Singhal-Et-Al Cavitation Model, set vaporization 3540Pa. Continue to caculate.
However,the residual of vf-phase-2(vapor) become zero soon and the residual line of it disappears.
My question is it possible the residual is zero and why? Is this result reasonable?
Looking forward your help. Thanks.
