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.
Table 1: Table of properties and references to the equations in (Concetta et al., 2015).
Properties | Equations | Equation/Table # |
---|---|---|
Melting point, (K) | 398 | Equation 2.1 |
Density, (kg/m^3) | Equation 2.30 | |
Viscosity, (Pa-s) | Equation 2.83 | |
Specific enthalpy, (J) | Equation 2.55 | |
Thermal Conductivity, (W/m-K) | Equation 2.91 | |
Isobaric Specific Heat, (J/kg-K) | Table 2.19.3 | |
Isentropic Bulk Modulus, (N/m) | Equation 2.44 | |
Speed of Sound, (m/s) | Table 2.19.3 |
Range of validity
