LeadBismuthFluidProperties

Fluid properties for Lead Bismuth eutectic 2LiF-BeF2

These properties are based on experiments reported in the Handbook on Lead-bismuth Eutectic Alloy and Lead Properties, Materials Compatibility, Thermal-hydraulics and Technologies (Concetta et al., 2015). Most properties only depend on temperature; the fluid is considered incompressible. The fluid properties are summarized in Table 1, which reports the formulas used and their origin.
