CO2 provides ideal gas thermodynamic properties for carbon dioxide valid over the temperature range from 200 K to 6000 K based on property information from McBride et al. (2002).  The reference state for specific enthalpy is based on the enthalpy of formation relative to the elements at 25 C.  The reference state for specific entropy is based on the Third Law of Thermodynamics.  The reference values are from:


Bonnie J. McBride, Michael J. Zehe, and Sanford Gordon

"NASA Glenn Coefficients for Calculating Thermodynamic Properties of Individual Species"

NASA/TP-2002-211556, Sept. 2002


Viscosity data are provided from the ideal gas contribution of the correlation from:

Laesecke, A. and Muzny,C.D.,

"Reference Correlation for the Viscosity of Carbon Dioxide"

J Phys Chem Ref Data. 2017 ; 46:  


The viscosity correlation is valide for temperatures between 100 K and 2000 K


Conductivity property correlations are implemented using data from:

 N.B. Vargaftik, Y.K. Vinogradov, V.S. Yargin, V.S., 

Handbook of Physical Properties of Liquids and Gases, 3rd ed, 1996, ISBN 1-56700-063-0.  

The thermal conductivity correlation is applicable for temperatures between 200 K and 1400 K.    


Note that CO2 provides thermodynamic properties assuming ideal gas behavior.  Use CARBONDIOXIDE OR R744 to provide real fluid properties in the subcooled, saturated mixture, and superheated regimes.
