Thermodynamic Properties of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone: Vapor Pressure, (p, ?, T) Behavior, and Speed of Sound Measurements, and Equation of State

We report comprehensive thermodynamic property measurements of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone. The p–ρ–T behavior was measured from T = (225 to 470) K with pressures up to 36 MPa using a two-sinker densimeter. These

Reference correlations for the viscosity and thermal conductivity of fluids over extended range of conditions: n-hexane in the vapor, liquid, and supercritical regions

This article summarizes the correlation procedures developed for IUPAC Project 2012-040-1-100 (Reference correlations for the thermal conductivity and viscosity of fluids over extended range of conditions (vapor, liquid and supercritical region)). This

Reference Correlation of the Thermal Conductivity of o-Xylene, m-Xylene, p-Xylene, and Ethylbenzene from the Triple Point to 700 K and Moderate Pressures

Sofia K. Mylona, K.D. Antoniadis, Marc J. Assael, Marcia L. Huber, Richard A. Perkins
This paper contains new, representative reference equations for the thermal conductivity of o-, m-, p- xylene and ethylbenzene. The equations are based upon a body of experimental data that has been critically assessed for internal consistency and for

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

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

Transport Properties of Fluids near Critical Points

June 5, 2014
Author(s)
Jan V. Sengers, Richard A. Perkins
This chapter reviews the currently available information concerning the behavior of transport properties near the vapor-liquid critical point of fluids and fluid mixtures. Special attention is devoted to the behavior of the thermal conductivity which

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

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
