Recommended viscosities of 11 dilute gases at 25?degC

December 13, 2012
Author(s)
Robert F. Berg, Michael R. Moldover
Commercially manufactured meters that measure the flow of a process gas are often calibrated with a known flow of a surrogate gas. This requires an accurate model of the flow meter and accurate values of the relevant thermophysical properties for both

ThermoData Engine (TDE): Software Implementation of the Dynamic Data Evaluation Concept. 8. Properties of Material Streams and Solvent Design

December 3, 2012
Author(s)
Vladimir Diky, Robert D. Chirico, Chris D. Muzny, Andrei F. Kazakov, Kenneth G. Kroenlein, Joe W. Magee, Ilmutdin M. Abdulagatov, Carlos A. Diaz-Tovar, Jeong W. Kang, Rafiqul Gani, Michael D. Frenkel
ThermoData Engine (TDE) is the first full-scale software implementation of the dynamic data evaluation concept, as reported in this journal. The present paper describes the first application of this concept to the evaluation of thermophysical properties for

Possibilities, Limits, and Tradeoffs for Refrigerants in the Vapor Compression Cycle

October 29, 2012
Author(s)
Mark O. McLinden, Andrei F. Kazakov, J S. Brown, Piotr A. Domanski, Jae H. Heo
We explore the possibilities for refrigerants having low global warming potential (GWP) using two distinct, but complimentary, approaches. In the first approach, we evaluate the effect of a refrigerant’s fundamental thermodynamic parameters on its

Second Virial Coefficients of H2 and its Isotopologues from a Six-Dimensional Potential

October 17, 2012
Author(s)
Giovanni Garberoglio, Piotr Jankowski, Krzysztof Szalewicz, Allan H. Harvey
We employ path-integral Monte Carlo techniques to compute the second virial coefficient as a function of temperature for molecular hydrogen (H2), deuterium (D2), and tritium (T2), along with the mixed isotopologues HD, HT, and DT. The calculations utilize

Dieseline for Supercritical Injection and Combustion in Compression-Ignition Engines: Volatility, Phase Transitions, Spray/Jet Structure, and Thermal Stability

September 20, 2012
Author(s)
Thomas J. Bruno, George G. Anitescu, Lawrence L. Tavlarides
To optimize the injection-combustion process of increasingly diversified fuels, thermophysical and chemical properties of new blends are required over wide range of compositions and P-T conditions, including supercritical (SC) states. In this study, the

Density and Speed of Sound Measurements of Four Bio-derived Fuels

September 13, 2012
Author(s)
Stephanie L. Outcalt, Tara J. Fortin
Compressed-liquid densities and ambient pressure densities and speeds of sound of four biomass-derived fuels have been measured. The compressed-liquid measurements were made from 270 K to 470 K, and 0.5 MPa to 50 MPa. The ambient pressure measurements were

New International Formulation for the Thermal Conductivity of H2O

Marcia L. Huber, Richard A. Perkins, Daniel G. Friend, Jan V. Sengers, Marc J. Assael, Ifigenia N. Metaxa, Kiyoshi Miyagawa, Robert Hellmann, Eckhard Vogel
The International Association for the Properties of Water and Steam (IAPWS) encouraged an extensive research effort to update the IAPS Formulation 1985 for the Thermal Conductivity of Ordinary Water Substance, leading to the adoption of a Release on the

Solubility of Water in 1-Octanol from 2 degC to 96 degC

July 25, 2012
Author(s)
Brian E. Lang
The solubility of water in 1-octanol was measured from 2 °C to 96 °C by coulometric Karl Fischer titration. The mass fraction solubility at 25 ° was found to be (48.91 ± 0.13) mg/g. Experiments also indicated the existence of a pseudo-equilibrium state

Reference Correlation of the Thermal Conductivity of Sulfur Hexafluoride from the Triple Point to 1000 K and up to 150 MPa

July 9, 2012
Author(s)
Marc J. Assael, I.A. Koini, K.D. Antoniadis, Marcia L. Huber, Ilmutdin M. Abdulagatov, Richard A. Perkins
This paper contains new, representative reference equations for the thermal conductivity of SF6. The equations are based in part upon a body of experimental data that has been critically assessed for internal consistency and for agreement with theory

Properties of Saturated Liquid D2O

This is a small section (two pages) for the next edition of the CRC Handbook of Chemistry and Physics.

Guidelines for reporting of phase equilibrium measurements (IUPAC Recommendations 2012)

April 27, 2012
Author(s)
Robert D. Chirico, Theodoor W. de Loos, Juergen Gmehling, Anthony R. Goodwin, Sumnesh Gupta, Kenneth N. Marsh, Calvin Spencer, Martin P. Trusler, William M. Haynes, Vicente Rives, Joan F. Brennecke
Recommendations are given for reporting in the primary scientific literature of measurements involving phase equilibrium. The focus is on documentation issues, and many of the recommendations may also be applied to the more general fields of thermodynamic
