to the Georgia Tech’s Thermophysical Properties Database for the Generation 3 Concentrating Solar Power (Gen3 CSP) program. The Gen3 CSP program was initiated by the U.S. Department of Energy Solar Energy Technologies Office in 2018 to advance high-temperature concentrating solar energy power technologies and reduce cost of CSP systems by increasing efficiency. The Georgia Tech team focused on measuring thermophysical  properties of potential heat transfer media and containment materials for this new CSP system. This database holds all of the thermal property measurements collected by our team and the Gen3 CSP collaborators. Along with interactive graphs, this database includes downloadable MS-Excel files of all data and documentation used when measuring these properties. The uncertainty analysis and error propagation are also included.

The tools used for these measurements include: Netzsch LFA 467 HT Hyperflash®, Netzsch STA 449 F3 Jupiter®, and a custom electrothermal immersion probe that utilized the 3 omega technique to measure the thermal conductivity and volumetric specific heat of heat transfer media.
