Pressure & Temperature dependent EOS
 
Does anyone whether it is possible to create or link a pressure and temperature dependent equation of state, i.e. p=f(rho,T) in fluent? I am trying to model a multiphase cryogenic flow so both temperature and pressure have a large enough effect that they must be considered. Most of the documentation I have read so far talks about defining density as a function of either temperature or pressure...
Thanks

Hi,

have you solved your problem? Because I have the same problem. I need to implement an EOS of water that p=p(rho,t).

Do you know how is it possible? Can I set a table of these parameters in fluent or i should write a UDF.
