I have not looked for this sort of data before for methane and ethane but they are pretty standard engineering gases so should be available. A hunt around and you should find it.

The Peng Robinson real gas model looks like it should be able to cover both vapour and liquid phases - can you use this real gas model to cover it? Which real gas model did you use before? Note I...

If they are both gasses then this should be easy with the multicomponent mixture model. If they start to change phase things are a lot more complex, but a...

CFX already has models to work out the properties of mixtures. If you are modelling a mixture then best define it as its constitutive gases and use a mixture model to work out the properties.

Setting the density as a function of P and T leads to some very complex terms in the Navier Stokes equations. For gases like ideal gas, and the real gas models these have been taken care of, but if...

Have a look at the real gas models in CFX. Also, your comments suggest you are looking for simply a variable density fluid (eg ideal gas), not a real gas.
