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

March 11, 2015
Author(s)
Richard A. Perkins, Marcia L. Huber, Marc J. Assael, Efthimia K. Mihailidou, Sofia K. Mylona, Evita J. Sykioti
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

An Equation of State for the Thermodynamic Properties of Cyclohexane

December 5, 2014

Yong Zhou, Jun Liu, Steven Penoncello, Eric Lemmon
In this work, an equation of state for cyclohexane has been developed using the Helmholtz energy as the fundamental property with independent variables of density and temperature. Multi-property fitting technology was used to fit the equation of state that

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

November 21, 2014
Author(s)
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

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

Sealed Gravitational Capillary Viscometers for Volatile Liquids

July 7, 2014
Author(s)
Arno R. Laesecke
The evolution of sealed gravitational capillary viscometers for measurements of volatile liquids is reviewed. Two corrections need to be applied to measurements with them: (i) the vapor buoyancy correction and, if coiled capillaries are used, (ii) the
