Solving bubble column using twoPhaseEulerFoam
 

HI,

I am trying to solve bubble column using twoPhaseEulerFoam.
In interfacialProperties file, they have given which model is to be used for calculating drag force and below that it is asked to mention dragPhase .

In a default case dragPhase is blended.

In my case I want to use dragModel only for dispersed phase (phase1).

So what change is required in place of blended.

I have tried it with "phase1" / "1" / .

But its not working. So please suggest the neccessory changes.
