SalineMoltenSaltFluidProperties
To use this object, you need to have the Saline library installed. Refer to the documentation for guidance on how to enable it. (Original description: Molten salt fluid properties using Saline)
The mole fractions of the various elements / molecules present in the salt must sum to one. The following properties can be computed:
density
isobaric specific heat
enthalpy
viscosity
thermal diffusivity
commentnote
Saline must be installed alongside MOOSE using the contrib/saline submodule in the Fluid Properties module to be able to use this fluid property object. To initialize/download the Saline submodule:
cd <directory where moose is downloaded>
git submodule update --init --checkout modules/fluid_properties/contrib/saline
Example input syntax
In this example, the fluid properties for a LiF-NaF-KF salt mixture are computed by a SalineMoltenSaltFluidProperties.
[FluidProperties]
[salt]
type = SalineMoltenSaltFluidProperties
comp_name = "LiF NaF KF"
comp_val = "0.465 0.115 0.42"
prop_def_file = "saline_custom.prp"
[]
[]
It leverages the salt property input data in the saline_custom.prp file below. The data is sorted in columns. The first column is the name of the salt, then its id, then a number of thermo-physical properties with additional metadata such as the range of validity, the uncertainty and a short name for the reference publication providing the data.
