Volumefraction in / out
 
Hi

In a two-phase(liquid/gas) simulation I have just one inlet and one outlet. I know the volumefraction of gas/liquid at the inlet, but the volumefraction on the outlet will change because of the pressuredrop(the liquid is inkompressible, the gas is not, massflow is the same). I'm looking for the pressuredrop. I still need to enter values for volumefraction at the outlet. Is there a better way to do it?

Is the flow supercritical at the outlet? If so, there's a supercritical outlet BC that can be used that doesn't require you to set the volume fractions. I think it's CCL only though (not in the GUI). Mike
