How much the value of secondary phase at the inlet

Hi fluent users:&lrm; I need to represent two phase oil-water flow into a pipe, I consider water flow in the &lrm;down part of the pipe and oil in the upper part. I consider water as secondary phase &lrm;and oil as primary but I have a problem to how should I put the value of volume fraction to the &lrm;secondary phase at the inlet of the pipe and what proper BC should I used? Anyone &lrm;can assist me in this problem?&lrm; Thanks a lot Khalid

Re: How much the value of secondary phase at the i

You can use as bc: velocity-inlet or mass flow inlet. There you can select the volume fraction of water (secondary phase for you). If you select water = 0.8, this means that oil is 0.2 at the inlet.
