BrineFluidProperties

Fluid properties for brine

A high-precision and consistent formulation for fluid properties for binary salt (NaCl) and water mixtures at pressures and temperatures of interest.

Density, enthalpy, internal energy and specific heat capacity are calculated using the formulations provided in Driesner and Heinrich (2007) and Driesner (2007).

Viscosity and thermal conductivity of brine are calculated using the formulation of Phillips et al. (1981).

Brine vapor pressure is calculated using the formulation presented in Haas Jr (1976).

Solubility of solid salt (halite) in water is given by Potter et al. (1977).

    C++ Type:std::vector

    Options:

    Description:Adds user-defined labels for accessing object parameters via control logic.

  • enableTrueSet the enabled status of the MooseObject.

    Default:True

    C++ Type:bool

    Options:

    Description:Set the enabled status of the MooseObject.

  • allow_duplicate_execution_on_initialFalseIn the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).

    Default:False

    C++ Type:bool

    Options:

    Description:In the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).

  • use_displaced_meshFalseWhether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.

    Default:False

    C++ Type:bool

    Options:

    Description:Whether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.
