Abstract Scope |
Molten salts are being considered for high temperature thermal energy storage and as a heat transfer fluid for several energy application such as concentrating solar power and nuclear reactor concepts. Quality thermophysical property data are critical for the design and deployment of these systems. These data are equally valuable for benchmarking predictive chemical modeling techniques. Existing property data for many salt systems are relatively scarce and challenging to measure. In this work, the density and viscosity of LiF-NaF-KF eutectic molten salt have been measured experimentally. Temperature and composition dependent Redlich-Kister functions have been used to generate binary interaction parameters in the LiF-NaF-KF system. These binary interactions have been used in the extrapolation of thermophysical properties of this ternary system. Details of the techniques and methods as well as the discussion of the results and comparison to existing computational and experimental data will be provided. |
