- drho_dp1.7324e-07derivative of density with respect to pressure (at constant temperature)
Default:1.7324e-07
C++ Type:double
Unit:(no unit assumed)
Controllable:No
Description:derivative of density with respect to pressure (at constant temperature)
FlibeFluidProperties
Fluid properties for flibe
Description
The FlibeFluidProperties class provides fluid properties for a peritectic molar composition of 67% LiF and 33% BeF, commonly referred to as 'flibe'.
Density is calculated from Richard et al. (2014), but with a pressure dependence added to ensure finite derivatives with respect to pressure needed by some applications. The partial derivative of density with respect to pressure is assumed to be 1.7324e-7 kg/m/Pa Richard et al. (2014), but this may be set to a user-defined value. Slightly increasing the partial derivative of density with respect to pressure may improve convergence of compressible flow equations without significantly affecting the physical accuracy of the density estimation Scarlat (2012). In the absence of the pressure dependence, the uncertainty on density is 0.05% Richard et al. (2014).
Viscosity, isobaric specific heat, and thermal conductivity are calculated with uncertainties of 20%, 2%, and 15%, respectively Richard et al. (2014). The viscosity of LiF and BeF vary by eight orders of magnitude, so caution should be used if applying these fluid properties to LiF-BeF mixtures with slightly different ratios Romatoski and Hu (2017).
Isochoric specific heat is calculated according to its definition as
which becomes, after substituting the definition for ,
Molar mass is calculated assuming 99.995% enrichment of lithium in the Li-7 isotope.
Range of Validity
These fluid properties are only applicable to liquid flibe. At atmospheric pressure, the melting and boiling points of flibe are approximately 458C and 1400C, respectively Richard et al. (2014). These fluid properties should not be used outside this range.
