Default a question about two phase simulation

hi everyone,

I am recently trying to simulate a liquid jet in a cross air flow.
Firstly I have chosen the Euler Euler solver: twoPhaseEulerFoam and bubbleFoam, and then I have als tested my case with the VOF solver iterFoam.

Here I have some questions about these solvers:

1. What is the difference between the two solvers twoPhaseEulerFoam and bubbleFoam? I have read somewhere that the twoPhaseEulerFoam includes the Kinetic Theory of Granular Flow. Can anyone give me some detailed information?

2. For bubbleFoam I need to give the diameter for the phase A and phase B. But how can I set these two value? e.g. when the phase A is the dispere phase, can I set the diameter of phase A equal to the diameter of the nozzel?

3.Is it possible that I can use these three solvers: twoPhaseEulerFoam, bubbleFoam, iterFoam to simulate the liquid break-up process?

thanks in advance
