The residual of vf -phase-2(vapor) become zero?

cuocuozhou · May 5, 2014, 03:12

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.

do you remember how did you solve this problem i am facing the same while simulating cavitation
