Properties of water and aqueous systems: Metrological applications

November 19, 2004
Author(s)
Daniel G. Friend, Allan H. Harvey
Water and aqueous systems are widely used in metrology, which is a major focus of the National Institute of Standards and Technology (NIST). Standards such as those produced by IAPWS can be used to calibrate instruments and validate protocols. In this work

Aqueous Solubility of Volatile Nonelectrolytes

July 1, 2004
Author(s)
Allan H. Harvey, M T. Fernandez-Diaz, J L. Alvarez
The thermodynamics of solution of voletile cormponents in water is reviewed and expressed both in terms of the Henry's constant and the vapor-liquid distribution coefficient. The procedures required to calculate these quantities from experimental data are

Physical Properties of Water

July 1, 2004
Author(s)
Allan H. Harvey, Daniel G. Friend
This chapter reviews the best current information about the thermophysical properties of the fluid phases of water, focusing particularlyon the way in which water's properties change with temperature and pressure at conditions relevant to high-temperature

Correlation for the Second Virial Coefficient of Water

March 4, 2004
Author(s)
Allan H. Harvey, Eric W. Lemmon
A new correlation has been developed to represent the second virial coefficient of water (H2O) as a function of temperature. The formulation was fitted to experimental data, both for the second virial coefficient itself and for a quantity related to its

Intermolecular Potential and Second Virial Coefficient of the Water-Hydrogen Complex

January 1, 2004
Author(s)
M P. Hodges, R J. Wheatley, G K. Schenter, Allan H. Harvey
We construct a rigid-body (5-dimensional) potential-energy surface for the water-hydrogen complex using scaled perturbation theory (SPT). An analytic fit of this surface is obtained, and using this, two minima are found: the global miniumum has C 2v

Molecular Dynamics Calculation of the Diffusivity of Sodium Chloride in Steam

January 1, 2003
Author(s)
Allan H. Harvey, Raymond D. Mountain
Molecular dynamics simulation is used to calculate the diffusivity of sodium chloride at infinite dilution in high-temperature steam at seven state points representing conditions of interest for the study of impurity deposition in steam turbines. Water is

Stream Tables

February 1, 2002
Author(s)
Allan Harvey
This article explains steam tables at an introductory technical level. After some historical meterial on the development of steam tables and their international standardization, the current standrds as adopted by the International Association for the

Intermolecular Potential and Second Virial Coefficient of the Water-Helium Complex

January 1, 2002
Author(s)
M P. Hodges, R J. Wheatley, Allan H. Harvey
A potential-energy surface for the water-helium complex is constructed from scaled perturbation theory calculations, and calibrated using accurate supermolecule methods. At the global minimum, the helium atom lies in the plane of the water molecule with an

Forum 2000: Fluid Properties for New Technologies, Connecting Virtual Design With Physical Reality

October 1, 2001
Author(s)
James C. Rainwater, Daniel G. Friend, Howard J. Hanley, Allan H. Harvey, C D. Holcomb, Arno R. Laesecke, Joe W. Magee, Chris D. Muzny
Forum 2000 was held at the 14th symposium for Thermophysical Properties, with all symposium attendees invited. The Forum addressed the present needs and prioities for thermophysical properties measurements and the challenges facing the experimental
