Simple question on twoPhaseEulerFoam

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 http://www.cfd-online.com/Forums/ope...tml#post187140 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 (http://www.cfd-online.com/Forums/ope...tml#post390746) I can find the answer.

And I had already read it...

Thanks anyway.
