Dear all,
I'm looking for a solver to simulate a flow through a nozzle in supersonic condition (about Mach 2) but with the possibility to evaluate the condensation of butane gas, due to conditions very close to the condensation of this gas.
As a starting point I'm considering sonicFoam solver, but I don't think it cover also the condensation possibility.
What do you suggest?

Moreover, how to implement the use of the Redlich-Kwong equation to consider the gas according to a real behaviour about calculating p, rho and T?
I read how to set a thermophysical model but it is not clear how to set a good one model for the butane. Is there a database where is possible to get a proper model for butane gas?
Moreover, I found some libraries, like this one but I don't know how to use them. Could anyone help on the way?
I'm just evaluating all possibilities I can have in OpenFOAM.

Thanks to who wants to help me!
