Thomas J. Bruno, Marcia L. Huber, Arno D. Laesecke, Eric Lemmon, Richard A. Perkins
This report describes measurement and modeling efforts performed on the missile fuel, JP-10. Measurements* include chemical analysis, thermal decomposition kinetics, density, viscosity, speed of sound, thermal conductivity and vapor pressure (distillation

Multiparameter Equations of State for Selected Siloxanes

April 25, 2006
Author(s)
P. Colonna, R. Nannan, A. Guardone, Eric Lemmon
The development of technical equations of state using the 12-parameter Span-Wagner functional form for four siloxanes is presented in two parts. The fluids under investigation include hexamethyldisiloxane (MM), tetradecamethylhexasiloxane (MD4M)

Short Fundamental Equations of State for 20 Industrial Fluids

April 11, 2006
Author(s)
Eric W. Lemmon, Roland Span
In a preceding project, functional forms for "short" Helmholtz equations of state for typical non- and weakly polar fluids and for typical polar fluids were developed by simultaneous optimization. The coefficients of these equations of state were fitted to

Standardized Equation for Hydrogen Gas Densities for Fuel Consumption Applications

April 3, 2006
Author(s)
Eric Lemmon, Marcia L. Huber, Daniel G. Friend, Carl Paulina
One of three currently recognized methods for evaluating the consumption of gaseous hydrogen fuel in vehicle applications involves the determination of the equilibrium temperature and pressure of the gas before and after usage within a storage tank of

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

January 11, 2005
Author(s)
Allan H. Harvey, Eric 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

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
