Hi guys,
I'm modeling a two-phase flow (gas-liq) in a pipe with 3' diameter in the Fluent.
I am using a flow patterns map.
I had success in the stratified and bubble regimes, but I have some problems for the plug flow. The regime doesn't form, it stay look like the stratified.
I'm using VOF model and an explicit method.

Someone can give an advice about this?

Thanks
