H2 provides ideal gas thermodynamic properties for hydrogen valid over the temperature range from 200 to 3500 K based on the property information in McBride et al. (2002).  The reference state for specific enthalpy is based on the enthalpy of formation relative to the elements at 25C.  The reference state for specific entropy is based on the Third Law of Thermodynamics.  The reference values are from:

Transport property correlations are based on tabular data available from:


Thermophysical Properties of Matter

Vol. 3:  Thermal Conductivity, Y.S. Touloukian, P.E. Liley, S.C. Saxena

Vol. 11: Viscosity,  Y.S. Touloukian, S.C. Saxena, and P. Hestermans

IFI/Plenun, NY, 1970, ISBN 0-306067020-8 


The range of validity of the viscosity correlation is between 10 K and 2000 K.  The thermal conductivity correlation covers the range between 20 and 1540 K.


Note that fluid H2 provides ideal gas properties.  Use fluid Hydrogen for real gas properties for hydrogen.
