After obtaining his Ph.D. at Berkeley, Dr. Harvey was a National Research Council Postdoctoral Associate for two years at NIST's Gaithersburg, Maryland facility, working with Dr. J.M.H. Levelt Sengers in the Thermophysics Division. He then worked in private industry for four years, implementing thermophysical properties and phase Equilibria in chemical process simulation software. In late 1994, he returned to NIST at its Boulder, Colorado facility. His work involves maintaining and improving NIST databases for fluid thermophysical properties, representing NIST in international research and standards efforts, and performing research to advance knowledge of fluid properties for metrology and industry. Outside of work, Allan enjoys reading, hiking and baseball, and is an Elder in his church.Research Interests:
Much of Dr. Harvey's research involves application of molecular modeling to predict thermophysical properties that are difficult to measure. He collaborates with theoretical chemists and physicists who produce first-principles intermolecular potential energy surfaces that can be used to calculate virial coefficients (corrections to the ideal gas law). Applications include mixtures of water with common gases (important for humidity standards, combustion gases, and CO2 sequestration) and higher virial coefficients of helium and argon (important in metrology).
Properties of carbon dioxide and CO2-rich mixtures are a focus of current research. This work is partially funded by the U.S. Department of Energy, and is geared toward properties needed for combustion and synthesis gases in advanced power cycles, properties for carbon capture and sequestration, and possible use of supercritical CO2 as a working fluid in solar, nuclear, and other power cycles.
Additional interests include properties of water in all its phases, and aqueous solutions with dissolved gases and/or electrolytes (such as seawater). Electrical and optical properties of fluid mixtures are also of interest, as is the application of thermodynamic theory to solve problems of environmental, industrial, or metrological importance.
