NEON provides thermodynamic properties for Neon using the fundamental equation of state described in the paper entitled "Thermodynamic Properties of Neon for Temperatures from the Triple Point to 700 K at Pressures to 700 MPa", Katti, R. Jacobsen, R.T, Stewart, R.B., and Jahangiri, M., Adv. Cyro. Eng.,  Vol 31, p. 1189, 1986


It appears that the ancillary equations provided in the above reference are in error.  Ancillary equations were fitted to the data provided in "Thermodynamic Properties of Refrigerants" by Stewart, R., Jacobsen, R., and Penoncello, S., ASHRAE, 1986, ISBN 0-910110-47-6


The values of specific enthalpy and entropy are, by default, referred to values of 0 at 298.15 K and 101.325 kPa.  The reference state can be changed using the $Reference directive.


Transport are based on the information provided in:

"Thermodynamic Properties of Refrigerants"

P.E. Liley and P.D. Desai, ASHRAE, ISBN 1-883413-10-9, 1993.  

These data are provided in the range from 25 K to 700 K for gases and from 25 K to 44 K for liquids and for surface tension.


Surface tension data are provided through a correlation developed by:
