Peng Robinson Equation of State and Varying Specific Heat
I am looking at solving a compressible case which involves a gas that does not behave like an ideal gas. I am therefore using the Peng-Robinson equation of state that requires the critical temperature and pressure along with an accentricity factor, I can find these values from literature.
Does anyone have experience of the Peng-Robinson EOS within Star CCM? If so, did you have success?
Also the constant pressure specific heat of the gas I am simulation changes quite drastically with both temperature and pressure. Is there a way in Star CCM+ of defining the specific heat as a function of both temperature and pressure? Or do people usually simplify the pressure-temperature relationship to a simpler polynomial?
