I tried setting the volume fraction at the outlet and letting the inlet volume fraction drift with the solution. Interestingly, some of the cases saw the inlet void drift to the measured inlet value...

I'd imagine that, in the experiment, inlet volume fraction was not something they directly controlled, but was a secondary effect of modifying the pumping...

The problem I'm seeing, the more I think about this, is that there is not really any physics in the pipe that could account for the volume fraction going to zero. Actually, there is not heat flux...

I will have to play around with these ideas today and report back when I get some results. I imagine it's possible that the vapor concentration goes to...

Out of my set of governing equations (vapor momentum, liquid momentum, vapor continuity, and liquid continuity), what derivative...

Replies: 13 On Boundary Conditions Views: 1,901 Posted By rks171 On Boundary Conditions I wrote a two-phase, 1-D CFD code. It has a segregated solver and a full coupled solver. I just can't seem to get the residuals to behave. They keep oscillating all over the place. Furthermore,...
