two phase modeling
Can Fluent take by itself the bubble/droplet coalescence and or break up in two phase gas -liquid models? to do that, what is needed to be done? how can i consider it in my model? do i have to write some kind of udf for that? can any one help me on this topic? Thaking you in advance....

Re: two phase modeling
No, FLUENT does not implement population balances by itself. To do what you want you need to implement them using UDF and UDS, but I don't think it's an easy task.

You can find some article in literature about population balances applied to multiphase flows. If you don't find them, ask me for them.

Hi :)

Re: two phase modeling

VOF model is able to capture any interphase deformation (like bubble/drop coalescence and break up) considering inertial and surface tension effects.
