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

CYCLE_D VERSION 4.0: Theoretical Vapor Compression Cycle Design Program

April 9, 2009
Author(s)
J S. Brown, Piotr A. Domanski, Eric Lemmon
This paper presents Version 4.0 of the CYCLE_D: NIST Vapor Compression Cycle Design Program. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line heat exchanger. In addition, the

THERMOPHYSICAL PROPERTIES OF FLUIDS

January 1, 2009
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

ThermoData Engine (TDE) version 3.0 (Pure Compounds, EOS, and Binary Mixtures)

December 31, 2008
Author(s)
Michael D. Frenkel, Robert D. Chirico, Chris Muzny, Andrei F. Kazakov, Eric Lemmon, Vladimir Diky
TheroData Engine (version 3.0) is expert-system software that implements the dynamic data evaluation concept for binary mixtures of molecular compounds. Evaluation of some reaction properties is also included.
