udf for multiphase flow with real gas mixture
dear all.....
i m working on the project inwhich i supposed to separate the oxygen(liquid) from air(liq-gas mix) with real gas model.. this multiphase flow in cryogenic conditions can be done by writing udf.. all i need that some help to initiate the problem... is that any udf tutorial available?
please help me..its urgent ..

Dear sugumaran,
I am working on Fluent multi-phase modelling for simulating Helium-Hydrogen mixing at cryogenic conditions.
The problem is, FLUENT does not allow the use of Real gases with any of the multi-phase models. So I suppose, I will have to use the multi-species model.
What do you think? Is there any other solution? How did you simulate your model?
Will I have to write any UDFs? If so for what purpose?
Please guide.

you can try CFX . In materials section, you can choose real gas models for refrigerants.
