Member Function Documentation

◆ assign()

template<class ScalarType , class FluidSystem >

template<class FluidState >

void Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::assign ( const FluidState & fs )

inline

Retrieve all parameters from an arbitrary fluid state.

Parameters

fs	Fluidstate

Note: If the other fluid state object is inconsistent with the thermodynamic equilibrium, the result of this method is undefined.

◆ averageMolarMass()

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::averageMolarMass ( int phaseIdx ) const

inline

The average molar mass \(\overline M_\alpha\) of phase \(\alpha\) in \(\mathrm{[kg/mol]}\).

The average molar mass is the mean mass of a mole of the fluid at current composition. It is defined as the sum of the component's molar masses weighted by the current mole fraction:

\[\mathrm{ \overline M_\alpha = \sum_\kappa M^\kappa x_\alpha^\kappa}\]

Since this is an immiscible fluidstate we simply consider the molarMass of the pure component/phase.

◆ density()

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::density ( int phaseIdx ) const

inline

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

◆ enthalpy()

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::enthalpy ( int phaseIdx ) const

inline

The specific enthalpy \(h_\alpha\) of a fluid phase \(\alpha\) in \(\mathrm{[J/kg]}\).

◆ fugacity() [1/2]

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::fugacity ( int compIdx ) const

inline

The fugacity of a component \(\mathrm{[Pa]}\).

This assumes chemical equilibrium.

◆ fugacity() [2/2]

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::fugacity	(	int	phaseIdx,
		int	compIdx
	)		const

inline

The fugacity \(f^\kappa_\alpha\) of component \(\kappa\) in fluid phase \(\alpha\) in \(\mathrm{[Pa]}\).

The fugacity is defined as: \(f_\alpha^\kappa := \Phi^\kappa_\alpha x^\kappa_\alpha p_\alpha \;,\) where \(\Phi^\kappa_\alpha\) is the fugacity coefficient [53] . The physical meaning of fugacity becomes clear from the equation:

\[f_\alpha^\kappa = p_\alpha \exp\left\{\frac{\zeta^\kappa_\alpha}{R T_\alpha} \right\} \;,\]

where \(\zeta^\kappa_\alpha\) represents the \(\kappa\)'s chemical potential in phase \(\alpha\), \(R\) stands for the ideal gas constant, and \(T_\alpha\) for the absolute temperature of phase \(\alpha\). Assuming thermal equilibrium, there is a one-to-one mapping between a component's chemical potential \(\zeta^\kappa_\alpha\) and its fugacity \(f^\kappa_\alpha\). In this case chemical equilibrium can thus be expressed by:

\[f^\kappa := f^\kappa_\alpha = f^\kappa_\beta\quad\forall \alpha, \beta\]

To avoid numerical issues with code that assumes miscibility, we return a fugacity of 0 for components which do not mix with the specified phase. (Actually it is undefined, but for finite fugacity coefficients, the only way to get components completely out of a phase is 0 to feed it zero fugacity.)

◆ fugacityCoefficient()

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::fugacityCoefficient	(	int	phaseIdx,
		int	compIdx
	)		const

inline

The fugacity coefficient \(\Phi^\kappa_\alpha\) of component \(\kappa\) in fluid phase \(\alpha\) in \(\mathrm{[-]}\).

Since we assume immiscibility, the fugacity coefficients for the components which are not miscible with the phase is infinite. Beware that this will very likely break your code if you don't keep that in mind.

◆ internalEnergy()

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::internalEnergy ( int phaseIdx ) const

inline

The specific internal energy \(u_\alpha\) of a fluid phase \(\alpha\) in \(\mathrm{[J/kg]}\).

The specific internal energy is defined by the relation:

\[u_\alpha = h_\alpha - \frac{p_\alpha}{\rho_\alpha}\]

◆ massFraction()

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::massFraction	(	int	phaseIdx,
		int	compIdx
	)		const

inline

Returns the mass fraction \(X^\kappa_\alpha\) of component \(\kappa\) in fluid phase \(\alpha\) in \(\mathrm{[-]}\).

They are set either 1 or 0 in a phase since this is an immiscible fluidstate.

Parameters

phaseIdx	the index of the phase
compIdx	the index of the component

◆ molarDensity()

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::molarDensity ( int phaseIdx ) const

inline

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

The molar density is defined by the mass density \(\rho_\alpha\) and the mean molar mass \(\overline M_\alpha\):

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

◆ molarity()

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::molarity	(	int	phaseIdx,
		int	compIdx
	)		const

inline

The molar concentration \(c^\kappa_\alpha\) of component \(\kappa\) in fluid phase \(\alpha\) in \(\mathrm{[mol/m^3]}\).

This quantity is usually called "molar concentration" or just "concentration", but there are many other (though less common) measures for concentration.

http://en.wikipedia.org/wiki/Concentration

◆ molarVolume()

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::molarVolume ( int phaseIdx ) const

inline

The molar volume \(v_{mol,\alpha}\) of a fluid phase \(\alpha\) in \(\mathrm{[m^3/mol]}\).

This quantity is the inverse of the molar density.

◆ moleFraction()

template<class ScalarType , class FluidSystem >

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::moleFraction	(	int	phaseIdx,
		int	compIdx
	)		const

inline

Returns the molar fraction \(x^\kappa_\alpha\) of the component \(\kappa\) in fluid phase \(\alpha\) in \(\mathrm{[-]}\).

The molar fraction \(x^\kappa_\alpha\) is defined as the ratio of the number of molecules of component \(\kappa\) and the total number of molecules of the phase \(\alpha\). They are set either 1 or 0 in a phase since this is an immiscible fluidstate.

Parameters

phaseIdx	the index of the phase
compIdx	the index of the component

◆ operator=() [1/2]

template<class ScalarType , class FluidSystem >

ImmiscibleFluidState & Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::operator= ( const ImmiscibleFluidState< ScalarType, FluidSystem > & fs )

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::partialPressure	(	int	phaseIdx,
		int	compIdx
	)		const

inline

The partial pressure of a component in a phase \(\mathrm{[Pa]}\).

To avoid numerical issues with code that assumes miscibility, we return a partial pressure of 0 for components which do not mix with the specified phase. Actually it is undefined.

Scalar Dumux::ImmiscibleFluidState< ScalarType, FluidSystem >::saturation ( int phaseIdx ) const

inline
