◆ averageMolarMass()

template<class FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::averageMolarMass ( int phaseIdx ) const

inline

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:

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

◆ density()

template<class FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::density ( int phaseIdx ) const

inline

◆ enthalpy()

template<class FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::enthalpy ( int phaseIdx ) const

inline

◆ fugacity()

template<class FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::fugacity	(	int	phaseIdx,
		int	compIdx
	)		const

inline

The fugacity is defined as: \(f_\alpha^\kappa := \Phi^\kappa_\alpha x^\kappa_\alpha p_\alpha \;,\) where \(\Phi^\kappa_\alpha\) is the fugacity coefficient [72] . 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:

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

◆ fugacityCoefficient()

template<class FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::fugacityCoefficient	(	int	phaseIdx,
		int	compIdx
	)		const

inline

◆ internalEnergy()

template<class FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::internalEnergy ( int phaseIdx ) const

inline

The specific internal energy is defined by the relation:

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

◆ massFraction()

template<class FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::massFraction	(	int	phaseIdx,
		int	compIdx
	)		const

inline

The mass fraction \(X^\kappa_\alpha\) is defined as the weight of all molecules of a component divided by the total mass of the fluid phase. It is related with the component's mole fraction by means of the relation

\[X^\kappa_\alpha = x^\kappa_\alpha \frac{M^\kappa}{\overline M_\alpha}\;,\]

where \(M^\kappa\) is the molar mass of component \(\kappa\) and \(\overline M_\alpha\) is the mean molar mass of a molecule of phase \(\alpha\).

Parameters

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

◆ molarDensity()

template<class FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::molarDensity ( int phaseIdx ) const

inline

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 FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::molarity	(	int	phaseIdx,
		int	compIdx
	)		const

inline

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 FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::molarVolume ( int phaseIdx ) const

inline

This quantity is the inverse of the molar density.

◆ moleFraction()

template<class FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::moleFraction	(	int	phaseIdx,
		int	compIdx
	)		const

inline

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 \(\alpha\).

Parameters

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

Scalar Dumux::PressureOverlayFluidState< FluidState >::pressure ( int phaseIdx ) const

◆ saturation()

template<class FluidState >

Scalar Dumux::PressureOverlayFluidState< FluidState >::saturation ( int phaseIdx ) const

inline

The saturation is defined as the pore space occupied by the fluid divided by the total pore space:

\[S_\alpha := \frac{\phi \mathcal{V}_\alpha}{\phi \mathcal{V}}\]

phaseIdx the index of the phase
