two phase flow
 
hi
I use ansys fluent.13 to simulate a two phase flow(water-air) .I choose VOF model .water is incompressible and air is compressible and I have two inlet by pressure inlet boundary( water:8.45 bar & air:2 bar) and one outlet by pressure outlet(1.4 bar) but I can't converge the problem
could you help me ?

what type of flow regime you working with? may you give more details about your problem?

Hi mhdmk,

Your simulation was just like mine, but my phases were argon and steel, I also chose VOF and k-epsilon model, but the k and epsilon were very hard to converge. Does your situation like mine? or your continuty and monument were also can not converge ?

You can decribe your model in detail, maybe we can help each other.:p
