Thermophysical properties are a key to efficiently and effectively designing the processes to produce and use the many fluids important in our economy, ranging from fuels to refrigerants to foodstuffs. However, while there are tens of thousands of fluids in use, some of them at the level of hundreds of millions of tonnes per year, good property data are available for only a few dozen fluids. A better understanding of fundamental fluid behavior would allow the accurate prediction of properties for those fluids lacking good data and thus enable their more efficient production and use. Improvement in fluid models require accurate experimental data, and the Thermophysical Properties of Fluids Group offers a range of state-of-the-art instrumentation operating over very wide ranges of temperature (up to 700oK) and pressure (up to 100oMPa). These include multiple instruments for the measurement of speed of sound and pressure-density-temperature properties. While our focus is on industrially important fluids, such as fuels and refrigerants, we also welcome proposals that would yield data primarily intended for model development, such as studies investigating the effects of molecular size, polarity, or extreme pressures. Both pure fluids and mixtures are of interest. Opportunities exist to expand the range and capabilities of our instruments. We especially encourage proposals that combine experimental studies with theory and modeling.
