The Thermodynamic Properties of Propane: From p-r-T to the Equation of State

September 14, 2010
Author(s)
Mark O. McLinden, Eric W. Lemmon
The p-ρ-T behavior of high-purity (99.999%) propane was measured from 265 K to 500 K with pressures to 36 Mpa using a two-sinker densimeter. The measurements extend from low-density vapor to compressed liquid states, and the near-critical region was

Thermodynamic, Transport, and Chemical Properties of Reference JP-8

Thomas J. Bruno, Marcia L. Huber, Arno R. Laesecke, Eric W. Lemmon, Mark O. McLinden, Stephanie L. Outcalt, Richard A. Perkins, Beverly L. Smith, Jason A. Widegren
This report contains a summary of research conducted to develop a standard or accepted set of thermophysical properties for the aviation kerosene, JP-8. This report is the culmination of a three year effort that included the participation of most of the

Surrogate Mixture Models for the Thermophysical Properties of Aviation Fuel Jet-A

May 27, 2010
Author(s)
Marcia L. Huber, Eric W. Lemmon, Thomas J. Bruno
We developed surrogate mixture models to represent the thermophysical properties of two samples of aviation turbine fuel Jet-A. One sample is a composite of numerous batches from a multiple manufacturers and is considered to be a representative fuel. A

Thermophysical Properties of Selected Fluids at Saturation

January 1, 2010
Author(s)
Eric W. Lemmon
These tables give thermodynamic and transport properties of a variety of fluids, as generated from the equations of state presented in the references below. The properties tabulated are pressure (P), density (ρ), enthalpy (H), entropy (S), isochoric heat

Effect of RP-1 Compositional Variability on Thermophysical Properties

October 6, 2009
Author(s)
Marcia L. Huber, Eric W. Lemmon, Thomas J. Bruno
We compare experimental and predicted thermophysical properties of two samples of rocket propellant RP-1 obtained from different batches of RP-1 that exhibit compositional variations. One sample is atypical, due to a high olefin content. The effect of the

Fundamental Equations of State for Parahydrogen, Normal Hydrogen, and Orthohydrogen

September 4, 2009
Author(s)
Jacob W. Leachman, Bryce Jacobson, Steven Penoncello, Eric Lemmon
If the potential for a boom in the global hydrogen economy is realized, there will be an increase in the need for accurate hydrogen thermodynamic property standards. Based on current and anticipated needs, new fundamental equations of state for

CYCLE_D: NIST Vapor Compression Cycle Design Program Version 4.0 Users' Guide

June 23, 2009
Author(s)
J S. Brown, Piotr A. Domanski, Eric Lemmon
The CYCLE_D package simulates vapor compression refrigeration cycles that use pure refrigerants or mixtures of refrigerants. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line

Model for Thermodynamic Properties of a Biodiesel Fuel

June 12, 2009
Author(s)
Marcia L. Huber, Eric W. Lemmon, Andrei F. Kazakov, Lisa S. Ott, Thomas J. Bruno
We present an equation-of-state approach to modeling the thermodynamic properties of a biodiesel fuel. Preliminary Helmholtz-type equations of state were developed with limited experimental data for five fatty acid methyl esters (FAMEs) that are primary
