droplets/bubbles
 

Hello friends, I have a two phase problem. A disk is rotating in a box and there is air and oil in it. There are oil droplets inside the air area and air bubbles in the oily area. Should I use the Eulerian model?

well depends on what you want to see. do you want to see the flow of the bubbles in the oil, meaning the exact movement/position ? depending on this you might want to use VOF or the eulerian model.

Dear friend thank you for your answer. I am interestend in the general situation.VOF is what i think also... My problem is heat transfer in a gear box. I have 2 disks that are in contact (instead of two gears). I have oil for lubrication and cooling of the disks and certainly air.... Anni
