Hi,

alpha=0 means phase a
alpha=1 means phase b

Whichever is the gas phase. Is it correct ?

Following http://www.tfd.chalmers.se/~hani/kur...PhaseEuler.pdf capt. 1.3 seems yes.

Quote:
The other fields that are present are alpha - volume fraction or void fraction which is ratio of volume of the discrete phase to that of the control volume
But in this thread TwoPhaseEulerFoam and Boundary conditions Raghavendra is working the opposite way.

Quote:
3) 3/4 th water (continous phase) filled so alpha being eual to 0 and remaining 1/4 air(discrete phase) and alpha being 1

Even a simple yes/no answer will be great, many thanks.

I think here (twoPhaseEulerFoam unphysical behaviour) I can find the answer.

And I had already read it...

Thanks anyway.
