A Reference Equation of State for Heavy Water

December 3, 2018
Author(s)
Stefan Herrig, Monika Thol, Allan H. Harvey, Eric Lemmon
An empirical fundamental equation of state is presented for heavy water (deuterium oxide, D2O). The equation is explicit in the reduced Helmholtz energy and allows the calculation of all thermodynamic properties over the whole fluid surface. It is valid

CYCLE_D: NIST Vapor Compression Cycle Design Program, Version 6.0; User's Guide

November 19, 2018
Author(s)
Piotr A. Domanski, J S. Brown, Eric W. Lemmon
The CYCLE_D package simulates vapor compression refrigeration cycles that use pure refrigerants or blends of refrigerants. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line heat

Vladimir Diky, Chris D. Muzny, Alexander Y. Smolyanitsky, Ala Bazyleva, Robert D. Chirico, Joe W. Magee, Yauheni Paulechka, Andrei F. Kazakov, Scott A. Townsend, Eric W. Lemmon, Michael D. Frenkel, Kenneth G. Kroenlein
The ThermoData Engine is a software expert system implementing the concept of dynamic data evaluation for thermophysical and thermochemical properties of, primarily, organic compounds. This new release provides a substantially expanded database of

An Analytical Solubility Model for Nitrogen-Methane-Ethane Ternary Mixtures

August 24, 2017
Author(s)
Jason Hartwig, Peter Meyerhofer, Ralph Lorenz, Eric Lemmon
Saturn's moon Titan has surface seas of liquid hydrocarbons and a thick, cold, nitrogen atmosphere, and is a target for future exploration. Critical to the design and operation of vehicles for this environment is knowledge of the amount of dissolved

Determination of the Thermodynamic Properties of Water from the Speed of Sound

October 21, 2016
Author(s)
J. P. Martin Trusler, Eric Lemmon
Thermodynamic properties of compressed liquids may be obtained from measurements of the speed of sound by means of thermodynamic integration subject to initial values of density and isobaric specific heat capacity along a single low-pressure isobar. In

A Helmholtz Energy Equation of State for Sulfur Dioxide

June 9, 2016
Author(s)
Kehui Gao, Jiangtao Wu, Penggang Zhang, Eric Lemmon
A Helmholtz energy equation of state with independent variables of temperature and density was developed for sulfur dioxide (SO2) based on thermodynamic property data from the literature. The equation of state is valid from the triple-point temperature of

This report summarizes the results of work performed under DOE/NETL Interagency Agreement DE- FE0003931, which began in October 2011 and ended (after a 6-month no-cost extension) March 31, 2015. The key objectives for this work were to: (1) Measure the dew

Density measurements of compressed-liquid dimethyl ether + pentane mixtures

January 1, 2016
Author(s)
Stephanie L. Outcalt, Eric W. Lemmon
Compressed-liquid densities of three compositions of the binary mixture dimethyl ether (CAS No. 115-10-6) + pentane (CAS No. 109-66-0) have been measured with a vibrating U-tube densimeter. Measurements were made at temperatures from 270 K to 390 K with
