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?

I will be modeling many dispersed bubbles.

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.
