Thermodynamic Properties of Neon for Temperatures from the Triple Point to 700 K at Pressures to 700 MPa

The published experimental data on the thermodynamic properties of neon have been used as the basis for a new thermodynamic property formulation for neon. The new correlation uses a fundamental equation (equation of state) explicit in Helmholtz energy, which provides for the calculation of derived thermodynamic properties by differentiation. The fundamental equation for neon is a subset of a larger comprehensive function which has also been used in developing thermodynamic property formulations for other fluids of cryogenic interest including oxygen, nitrogen, argon, and ethylene. In addition, new equations for the vapor pressure, saturated liquid density, and saturated vapor density are presented. The formulation presented here may be used to calculate pressure, density, temperature, enthalpy, entropy, internal energy, isochoric and isobaric heat capacities, and velocity of sound for neon. Summary comparisons of properties calculated with the new formulation for neon with selected experimental data are included to verify the accuracy of the fundamental equation for calculation of thermodynamic properties.
