Hi, I am wondering if it's possile to model inlet with a mixture of water and tiny bubbles?

I am modeling a water treatment reactor filled with water.

Again Inlet is a mixture of water and tiny bubbles. Thanks in advance.

Yes you can.

You can use multiphase flow algebraic slip mixture model and define volumetric fraction of air at the inlet.

Thanks million. You are my life saver. Actually, I had little idea with that stuff. And I am also wondering if it is possbile to define the diameter of bubble in the multiphase flow algebraic slip model. Can U comment on this matter?

Thanks in advance!!!

I now I get the hang of it. multiphase flow algebraic slip model aske me to input diamenter of second phase material. One other thing. When do we really have to have "Body formce" enabled? I am always confused when it come to this pain in the neck. Thanks in advance smart guys..
