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

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

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

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
