Progress toward new Reference Correlations for the Transport Properties of Carbon Dioxide

September 10, 2014
Author(s)
Allan H. Harvey, Marcia L. Huber, Arno R. Laesecke, Chris D. Muzny, Richard A. Perkins
The thermophysical properties of carbon dioxide are essential for accurate process design and optimization. While the thermodynamic properties of CO2 are available with excellent accuracy from the reference-quality equation of state of Span and Wagner, the

Mass diffusion of organic fluids: a molecular dynamics perspective

May 31, 2013
Author(s)
Alexander Y. Smolyanitsky, Andrei F. Kazakov, Thomas J. Bruno, Marcia L. Huber
A well-established interaction potential, the Optimized Potential for Liquid Simulation All-Atom (OPLS-AA) force-field, within the MD framework was used to determine self- and mutual diffusivity of several near-critical and supercritical fluids. The test

Correlation for the Viscosity of Hydrogen obtained from Symbolic Regression

March 27, 2013
Author(s)
Chris D. Muzny, Marcia L. Huber, Andrei F. Kazakov
We report the results of a symbolic regression methodology to obtain both the functional form and the coefficients for a wide-ranging correlation for the viscosity of normal hydrogen. The correlation covers the temperature range from the triple point

Critical thermal-conductivity enhancement in molecular fluids

March 2, 2013
Author(s)
Richard A. Perkins, Jan V. Sengers, Ilmutdin M. Abdulagatov, Marcia L. Huber
The available information for the thermal-conductivity enhancement is reviewed. We show that it can be represented by a simplified solution of the mode-coupling theory of critical dynamics with two critical amplitudes and one cutoff wave number as fluid

Experimental Study of the Thermal Conductivity of Water +Ammonia Refrigerant Mixtures at Temperatures from 278 K to 356 K and at Pressures up to 20 MPa

February 28, 2013
Author(s)
F. N. Shamsetdinov, Z. I. Zaripov, Ilmutdin M. Abdulagatov, Marcia L. Huber, F. M. Gumerov, F. R. Gabitov, Andrei F. Kazakov
The thermal conductivity of binary water + ammonia mixtures was measured over the temperature range from 278 K to 356 K and at pressures up to 20 MPa using the steady-state hot-wire method. Measurements were made for eight compositions over the entire

Experimental investigation of Low-pressure refrigerant mixtures for Micro Cryogenic Coolers

February 4, 2013
Author(s)
Ryan J. Lewis, Yunda Wang, Peter E. Bradley, Marcia L. Huber, Ray Radebaugh, Y. C. Lee
Micro Cryogenic Coolers (MCCs) can achieve very small sizes and high efficiencies when operating with a refrigerant mixture, but micro-scale compressors have a limited pressure output. Four refrigerant mixtures were designed to operate between 0.4 MPa and

New International Formulation for the Thermal Conductivity of H2O

August 23, 2012
Author(s)
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

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

Methodology for Formulating Diesel Surrogate Fuels with Accurate Compositional, Ignition-Quality, and Volatility Characteristics

May 14, 2012
Author(s)
Charles J. Mueller, William J. Cannella, Thomas J. Bruno, Bruce Bunting, Heather Dettman, James A. Franz, Marcia L. Huber, Mani Natarajan, William J. Pitz, Matthew A. Ratcliff, Ken Wright
In this work a novel approach is developed to formulate surrogate fuels having characteristics that are representative of diesel fuels produced from real-world refinery streams. Because diesel fuels consist of hundreds of compounds, it is difficult to

Measurements and Modeling Study on a High-Aromatic Diesel Fuel

January 31, 2012
Author(s)
Bret Windom, Marcia L. Huber, Thomas J. Bruno, A L. Lown, C T. Lira
The increasing cost of diesel fuel, potential for supply disruptions, and environmental concerns have resulted in a great deal of research to improve the performance and efficiency of diesel engines. This includes significant efforts in the reformulation

DEMONSTRATION OF AN INTEGRATED MICRO CRYOGENIC COOLER AND MINIATURE COMPRESSOR FOR COOLING TO 200 K

November 17, 2011
Author(s)
Ryan J. Lewis, Mu Hong Lin, Yunda Wang, Jill Cooper, Peter E. Bradley, Ray Radebaugh, Marcia L. Huber, Yung-Cheng Lee
Joule-Thompson (J-T) based micro cryogenic coolers (MCCs) are attractive because they can provide the cryogenic temperatures needed for small electronic devices while having a low cost and small volumetric footprint. A compressor is a major part of a
