Development of measurement capabilities for the thermophysical properties of energy-related fluids. Annual report, December 1, 1990--November 30, 1991
The objectives of this project are to develop state-of-the-art experimental apparatus that can be used to measure the thermophysical properties of a wide range of fluids and fluid mixtures important to the energy, chemical, and energy-related industries and to carry out carefully selected benchmark measurements on key systems. The measurement capabilities to be developed include new apparatus for transport properties, thermodynamic properties, phase equilibria properties, and dielectric properties. The specific measurement capabilities to be developed are: thermal conductivity apparatus; vibrating wire viscometer; dual-sinker densimeter; high-temperature vibrating tube densimeter; dynamic phase equilibria apparatus; apparatus for dilute solutions; total-enthalpy flow calorimeter; and dielectric constant apparatus. The research also includes benchmark experimental measurements on pure and mixed alternative refrigerants and their mixtures with lubricants, on aqueous solutions, and on carefully selected systems consisting of species of diverse size (methane + neopentane) and polarity (methane + ammonia) that are important for the development of predictive models for energy-related fluids.
