Hi, Can any one suggest me about which model to use?

I will modeling air bubble in water. Water is the primary phase. Also i will use K-e model for turbulence. I can't figure out which one to use---DPM or Mixture.

Thanks for any help.

Are you modeling dispersed air bubbles or one large air bubble?

you can use the Eulerian or Mixture multiphase model for this. If there is significant slip velocity between phases I would recommend using the Eulerian model.
