◆ pseudo3DWallFriction() [2/2]

template<class TypeTag >

Scalar Dumux::NavierStokesMomentumProblemImpl< TypeTag, DiscretizationMethods::FCStaggered >::pseudo3DWallFriction	(	const Scalar	velocity,
		const Scalar	viscosity,
		const Scalar	height,
		const Scalar	factor = `8.0`
	)		const

inlineinherited

An additional drag term can be included as source term for the momentum balance to mimic 3D flow behavior in 2D:

\[ f_{drag} = -(8 \mu / h^2)v \]

Here, \(h\) corresponds to the extruded height that is bounded by the imaginary walls. See Flekkoy et al. (1995) [24]
A value of 8.0 is used as a default factor, corresponding to the velocity profile at the center plane of the virtual height (maximum velocity). Setting this value to 12.0 corresponds to an depth-averaged velocity (Venturoli and Boek, 2006) [74].

◆ referencePressure()

template<class TypeTag >

Scalar Dumux::NavierStokesMomentumProblemImpl< TypeTag, DiscretizationMethods::FCStaggered >::referencePressure	(	const Element &	element,
		const FVElementGeometry &	fvGeometry,
		const SubControlVolumeFace &	scvf
	)		const

inlineinherited

Returns a reference pressure at a given sub control volume face. This pressure is subtracted from the actual pressure for the momentum balance which potentially helps to improve numerical accuracy by avoiding issues related do floating point arithmetic.

Note: Overload this for reference pressures other than zero.

◆ scvPointSources()

template<class TypeTag >

template<class ElementVolumeVariables >

NumEqVector Dumux::FVProblem< TypeTag >::scvPointSources	(	const Element &	element,
		const FVElementGeometry &	fvGeometry,
		const ElementVolumeVariables &	elemVolVars,
		const SubControlVolume &	scv
	)		const

inlineinherited

Adds contribution of point sources for a specific sub control volume to the values. Caution: Only overload this method in the implementation if you know what you are doing.

◆ setName()

template<class TypeTag >

void Dumux::FVProblem< TypeTag >::setName ( const std::string & newName )

inlineinherited

Set the problem name.

This static method sets the simulation name, which should be called before the application problem is declared! If not, the default name "sim" will be used.

Parameters

newName The problem's name

◆ source() [1/2]

template<class TypeTag >

template<class ElementVolumeVariables >

NumEqVector Dumux::FVProblem< TypeTag >::source	(	const Element &	element,
		const FVElementGeometry &	fvGeometry,
		const ElementVolumeVariables &	elemVolVars,
		const SubControlVolume &	scv
	)		const

inlineinherited

Evaluate the source term for all phases within a given sub-control-volume.

This is the method for the case where the source term is potentially solution dependent and requires some quantities that are specific to the fully-implicit method.

Parameters

element	The finite element
fvGeometry	The finite-volume geometry
elemVolVars	All volume variables for the element
scv	The sub control volume

For this method, the return parameter stores the conserved quantity rate generated or annihilate per volume unit. Positive values mean that the conserved quantity is created, negative ones mean that it vanishes. E.g. for the mass balance that would be a mass rate in \( [ kg / (m^3 \cdot s)] \).

◆ source() [2/2]

template<class TypeTag >

Sources Dumux::NavierStokesMomentumProblemImpl< TypeTag, DiscretizationMethods::FCStaggered >::source	(	const Element &	element,
		const FVElementGeometry &	fvGeometry,
		const ElementVolumeVariables &	elemVolVars,
		const SubControlVolume &	scv
	)		const

inlineinherited

Evaluate the source term for all phases within a given sub-control-volume.

This is the method for the case where the source term is potentially solution dependent and requires some quantities that are specific to the fully-implicit method.

Parameters

element	The finite element
fvGeometry	The finite-volume geometry
elemVolVars	All volume variables for the element
scv	The sub control volume

For this method, the return parameter stores the conserved quantity rate generated or annihilate per volume unit. Positive values mean that the conserved quantity is created, negative ones mean that it vanishes. E.g. for the mass balance that would be a mass rate in \( [ kg / (m^3 \cdot s)] \).

◆ sourceAtPos()

template<class TypeTag >

Sources Dumux::NavierStokesMomentumProblemImpl< TypeTag, DiscretizationMethods::FCStaggered >::sourceAtPos ( const GlobalPosition & globalPos ) const

inlineinherited

Evaluate the source term for all phases within a given sub-control-volume.

Parameters

globalPos The position of the center of the finite volume for which the source term ought to be specified in global coordinates

For this method, the values parameter stores the conserved quantity rate generated or annihilate per volume unit. Positive values mean that the conserved quantity is created, negative ones mean that it vanishes. E.g. for the mass balance that would be a mass rate in \( [ kg / (m^3 \cdot s)] \).

As a default, i.e. if the user's problem does not overload any source method return 0.0 (no source terms)

◆ spatialParams() [1/2]

template<class TypeTag >

SpatialParams & Dumux::FVProblemWithSpatialParams< TypeTag >::spatialParams ( )

inlineinherited

Return a reference to the underlying spatial parameters.

◆ spatialParams() [2/2]

template<class TypeTag >

const SpatialParams & Dumux::FVProblemWithSpatialParams< TypeTag >::spatialParams ( ) const

inlineinherited

Return a reference to the underlying spatial parameters.
