OXYGEN provides thermodynamic properties using the Fundamental equation of state developed by R.B. Stewart, R.T. Jacobsen, and W. Wagner, "Thermodynamic Properties of Oxygen from the Triple Point to 300 K with Pressures to 80 MPa", J. Phys, Chem, Ref. Data, Vol. 20, No. 5, 1991.
Note that OXYGEN provides thermodynamic properties assuming real fluid behavior. The reference state for ideal gas specific enthalpy and entropy is 0 kJ/kmol and 0 kJ/kmol-K respectively at 298.15 K and 101.325 kPa.
The upper limit on the temperature range of applicability has been set to 2000 K, which is much beyond the 300 K in the publication. Tests from NIST (communicated by Eric Lemmon) indicate that the equation of state can be accurately applied at higher temperatures.
Use O2 for ideal gas properties of oxygen consistent with reference states used in combustion calculations.
