Welcome
The Experimental Properties of Fluids Group provides the underlying measurement infrastructure for thermodynamic and transport properties of fluids (gaseous and liquid) that is required by industry and government. The Group develops and maintains high accuracy instruments and apparatus for a wide range of pure fluids and fluid mixtures. We cover nonpolar, polar, dipolar aprotic, and aqueous fluids that may consist of one component, or many hundreds of components. Our measurements extend over wide ranges of temperature, pressure and composition. We apply our instrumentation to technically important fluids (fuels, working fluids, etc.) that are critical to industry. All of our work is closely integrated with the activities of the Theory of Fluids Group (which develops thermodynamic and transport property models for fluid properties), and the Thermodynamics Research Center, (which develops the largest thermophysical property databases). Our efforts are leveraged by collaboration with universities, industry consortia, and standards organizations. In addition to providing the Division's analytical chemistry laboratory, NMR laboratory (Nuclear Magnetic Resonance), and calibration facility, the Group's research activities are in four main areas.
Programs/Projects
Working/Functional Fluids—The conversion of primary energy (e.g. heat generated by the combustion of a fuel) into useful work most often involves a working fluid operating in a thermodynamic cycle. Examples include a steam … Energetic Materials—Energetic materials, as distinct from fuels, include explosives, propellants and ignitable liquids. One typically associates the study of energetic materials with forensics, in the … Fuels—Energy is one of the most critical problems facing the United States, with technical, economic and public policy aspects. Decision makers depend on reliable and objective characterization of fuels … Standard Reference Fluid Measurements—Property measurements of the very highest accuracies are important for developing the thermodynamic and transport property models for working fluids and reference fluids. More than simply providing … |
