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

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

Data for Thermophysical Properties of Humid Gases in Power Cycles

June 20, 2011
Author(s)
Allan H. Harvey, Mark O. McLinden, Richard A. Perkins
This report summarizes the results of work performed for DOE/NETL Interagency Agreement DE-AI26-06NT42957. The key objectives for this work were to: (1) Use results of first-principles quantum mechanics to develop a description of the thermodynamics of

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

July 14, 2010
Author(s)
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

Thermal Diffusivity of H2O near the Critical Point

September 25, 2009
Author(s)
Jan V. Sengers, Richard A. Perkins, Marcia L. Huber, Bernard Le Neindre
The asymptotic critical behavior of the thermal diffusivity of H 2O, deduced from dynamic light-scattering measurements, is shown to be in good agreement with the mode-coupling theory for critical dynamics in fluids. Consistency of the thermal-diffusivity

New International Formulation for the Viscosity of H2O

April 21, 2009
Author(s)
Marcia L. Huber, Richard A. Perkins, Arno R. Laesecke, Daniel G. Friend, Jan V. Sengers, Marc J. Assael, Ifigenia N. Metaxa, Eckhard Vogel, Radim Mares, Kiyoshi Miyagawa
The International Association for the Properties of Water and Steam (IAPWS) encouraged an extensive research effort to update the IAPS Formulation 1985 for the Viscosity of Ordinary Water Substance, leading to the adoption of a Release on the IAPWS

Viscosity of H20 in the Critical Region

April 15, 2009
Author(s)
Jan V. Sengers, Richard A. Perkins, Marcia L. Huber, Daniel G. Friend
It has been well established that thermodynamic and transport properties of fluids exhibit singular behavior near the critical point. In this paper we review the theoretical predictions for the enhancement of the viscosity near the critical point. It is

Thermophysical Properties Measurements and Models for Rocket Propellant RP-1: Phase I

February 1, 2007
Author(s)
Joe W. Magee, Thomas J. Bruno, Daniel G. Friend, Marcia L. Huber, Arno D. Laesecke, Eric Lemmon, Mark O. McLinden, Richard A. Perkins, J?rg Baranski, Jason A. Widegren
Accurate knowledge of thermophysical properties is a prerequisite to design efficient and cost-effective rocket engine systems that use the kerosene rocket propellant designated RP-1. A robust properties model that is based on reliable experimental

Thermochemical and Thermophysical Properties of JP-10
