Method for Estimating the Dielectirc Constant of Natural Gas Mixtures

January 11, 2005
Author(s)
Allan H. Harvey, Eric W. Lemmon
A method is developed for calculating the static dielectric constant (relative permittivity) of fluid mixtures, with an emphasis on natural gas. The dielectric constant is calculated as a function of temperature, density, and composition; the density is

Correlation for the Second Virial Coefficient of Water

March 4, 2004
Author(s)
Allan H. Harvey, Eric W. Lemmon
A new correlation has been developed to represent the second virial coefficient of water (H2O) as a function of temperature. The formulation was fitted to experimental data, both for the second virial coefficient itself and for a quantity related to its

A Fundamental Equation for Trifluoromethane (R-23)

December 1, 2003
Author(s)
S G. Penoncello, Eric Lemmon, R. T. Jacobsen, Z Shan
A formulation for the thermodynamic properties of trifluoromethane R-23) is presented. The equation is valid for single-phase and saturation states from the triple point (1 18.02 K) to 475 K at pressures up to 120 MPa. The formulation includes an equation

The Refprop Database for the Thermophysical Properties of Refrigerants

September 14, 2003
Author(s)
Mark O. McLinden, Eric W. Lemmon, Marcia L. Huber
Property databases are widely used for the design and analysis of refrigeration systems. Version 7 of the NIST REFPROP Reference Fluid Thermodynamic and Transport Properties) database is described. Compared with previous versions, the database includes

Thermophysical Properties of Materials

January 1, 2003
Author(s)
R. T. Jacobsen, Eric Lemmon, S G. Pennoncello, Z Shan
This chapter presents tables of values of the thermodynamic and transport properties of fluids.

Method for Estimating Mixture Equation of State Parameters

November 1, 2001
Author(s)
Eric W. Lemmon, Mark O. McLinden
A predictive method for estimating the zij parameter in the mixture model of Lemmon and Jacobsen [Int. J. Thermophysics 20:1629 (1999)] has been developed. Data for 76 binary pairs have been used in the development of this method, and these data are

Multiparameter Equations of State - Recent Trends and Future Challenges

July 1, 2001
Author(s)
R Span, Wolfgang Wagner, Eric Lemmon, R Jacobsen
The purpose of this article is to update the common knowledge on characteristic features of empirical multi-parameter equations of state, to increase the confidence of potential users, and possibly to attract other scientists to theoretical and

Thermodynamic Properties of Air from 60 to 2000 K at Pressures up to 2000 Mpa

October 1, 1999
Author(s)
M D. Panasiti, Eric Lemmon, S G. Penoncello, R. T. Jacobsen, Daniel G. Friend
A thermodynamic property formulation for standard dry air based upon experimental P-p-T, heat capactiy, and speed of sound data and predicted values, which extends the range of prior formulations to higher pressures and temperatures, is presented.
