I am doing a project about two phase flow (oil-water-gas) in a hilly terrain pipe. I have some doubt whether the FLUENT can simulate this flow phenomenon or not?

Normally fluent 6 will perform this kind of simulation. But I do't know for Fluent 5.

You should be a bit more precise with your question to get a usefull answer.

How do you want to treat the water-oil-emulsion. As one fluid or as two fluids which try to separate during the flow? How much gas and in which form (bubbles or dissolved) do you have?

Isn't this the realm of simultion programs like OLGA2000? Check out:

Dear sir I am MSc student in petroleum engineering at Petroleum University of Technology(P.U.T). I want information about three phase releative permeability and their behavoir in porous media.

Dear Samaneh This is the wrong forum for trying to get an answer to your question.

There are many books and papers published on this subject. Try the search engine for "relative permeability", or "reservoir engineering".

I hope that this is useful.
