The molar density \(\rho_{mol,\alpha}\) of the fluid phase \(\alpha\) in \(\mathrm{[mol/m^3]}\).

The molar density for the simple relation is defined by the mass density \(\rho_\alpha\) and the average molar mass of the phase \(M_\alpha\):

\[\rho_{mol,\alpha} = \frac{\rho_\alpha}{M_\alpha} \;.\]

◆ thermalConductivity() [3/3]

template<class Scalar , class H2OType = Components::TabulatedComponent<Dumux::Components::H2O<Scalar>>>

template<class FluidState >

static Scalar Dumux::FluidSystems::Brine< Scalar, H2OType >::thermalConductivity	(	const FluidState &	fluidState,
		int	phaseIdx
	)

inlinestatic

Thermal conductivity of a fluid phase \(\mathrm{[W/(m K)]}\).

Parameters

fluidState	An arbitrary fluid state
phaseIdx	The index of the fluid phase to consider

The thermal conductivity of brine is implemented based on the contribution of NaCl ( \(\lambda_{brine}\)/ \(\lambda_{H_2O}\)) of [81] https://link.springer.com/content/pdf/10.1007/BF00867119.pdf, also discussed in [53] https://docecity.com/thermal-conductivity-of-aqueous-sodium-chloride-acs-publicat-5f10766acba00.html

◆ vaporPressure()

template<class Scalar , class H2OType = Components::TabulatedComponent<Dumux::Components::H2O<Scalar>>>

template<class FluidState >

static Scalar Dumux::FluidSystems::Brine< Scalar, H2OType >::vaporPressure	(	const FluidState &	fluidState,
		int	compIdx
	)

inlinestatic

Vapor pressure of a component \(\mathrm{[Pa]}\).

Note: The vapor pressure of brine decreases with the mole fraction of water in the liquid phase. This is described by Raoult's law, see Thomas Fetzer's Dissertation Eq. 2.11. It is also the simplified version of the Kelvin equation, without the influence of the capillary pressure as we have one-phase flow.

Parameters

fluidState	The fluid state
compIdx	The index of the component to consider

◆ viscosity() [1/3]

template<class Scalar , class H2OType = Components::TabulatedComponent<Dumux::Components::H2O<Scalar>>>

template<class FluidState >

static Scalar Dumux::FluidSystems::Base< ScalarType, Implementation >::viscosity	(	const FluidState &	fluidState,
		const ParameterCache &	paramCache,
		int	phaseIdx
	)

inlinestatic

Calculate the dynamic viscosity of a fluid phase \(\mathrm{[Pa*s]}\).

Parameters

fluidState	The fluid state
paramCache	mutable parameters
phaseIdx	Index of the fluid phase

◆ viscosity() [2/3]

template<class Scalar , class H2OType = Components::TabulatedComponent<Dumux::Components::H2O<Scalar>>>

template<class FluidState >

static Scalar Dumux::FluidSystems::Base< ScalarType, Implementation >::viscosity	(	const FluidState &	fluidState,
		int	phaseIdx
	)

inlinestatic

Calculate the dynamic viscosity of a fluid phase \(\mathrm{[Pa*s]}\).

Parameters

fluidState	The fluid state
phaseIdx	Index of the fluid phase

◆ viscosity() [3/3]

template<class Scalar , class H2OType = Components::TabulatedComponent<Dumux::Components::H2O<Scalar>>>

template<class FluidState >

static Scalar Dumux::FluidSystems::Brine< Scalar, H2OType >::viscosity	(	const FluidState &	fluidState,
		int	phaseIdx = `liquidPhaseIdx`
	)

inlinestatic

Return the viscosity of the phase.

Note: The viscosity is computed as a function of the salt mass fraction and temperature. The used function is an empirical relationship fitted to experimental data. It is presented by Batzle and Wang, 1992 (DOI: 10.1190/1.1443207) [8], better description and comparison with other approaches in Adams and Bachu, 2002 (DOI: 10.1046/j.1468-8123.2002.00041.x) [2]. However, the equation given in Adams and Bachu, 2002(DOI: 10.1046/j.1468-8123.2002.00041.x) [2] is obviously wrong when compared to the original by Batzle and Wang, 1992 (DOI: 10.1190/1.1443207) [8].
