Description

template<class TypeTag>
class Dumux::FV2dPressure2P2CAdaptive< TypeTag >

The finite volume model for the solution of the compositional pressure equation.

Provides a Finite Volume implementation for the pressure equation of a compressible system with two components. An IMPES-like method is used for the sequential solution of the problem. Diffusion is neglected, capillarity can be regarded. Isothermal conditions and local thermodynamic equilibrium are assumed. Gravity is included.

$c_{total}\frac{\partial p}{\partial t} + \sum_{\kappa} \frac{\partial v_{total}}{\partial C^{\kappa}} \nabla \cdot \left( \sum_{\alpha} X^{\kappa}_{\alpha} \varrho_{\alpha} \bf{v}_{\alpha}\right) = \sum_{\kappa} \frac{\partial v_{total}}{\partial C^{\kappa}} q^{\kappa},$

where $\bf{v}_{\alpha} = - \lambda_{\alpha} \bf{K} \left(\nabla p_{\alpha} + \rho_{\alpha} \bf{g} \right)$ . $c_{total}$ represents the total compressibility, for constant porosity this yields $- \frac{\partial V_{total}}{\partial p_{\alpha}}$ , $p_{\alpha}$ denotes the phase pressure, $\bf{K}$ the absolute permeability, $\lambda_{\alpha}$ the phase mobility, $\rho_{\alpha}$ the phase density and $\bf{g}$ the gravity constant and $C^{\kappa}$ the total Component concentration. See paper SPE 99619 or "Analysis of a Compositional Model for Fluid Flow in Porous Media" by Chen, Qin and Ewing for derivation. The partial derivatives of the actual fluid volume $v_{total}$ are gained by using a secant method.

This adaptive implementation uses its own initialization and assembling methods for matrix and right-hand-side vector, but solution is done by the base class FVPressure. Fluxes near hanging nodes can be calculated using an mpfa method.

◆ getFlux()

template<class TypeTag >

void Dumux::FVPressure2P2C< TypeTag >::getFlux	(	EntryType &	entries,
		const Intersection &	intersection,
		const CellData &	cellDataI,
		const bool	first
	)

inherited

Get flux at an interface between two cells.

for first == true, the flux is calculated in traditional fractional-flow forn as in FVPressure2P. for first == false, the flux thorugh $\gamma$ is calculated via a volume balance formulation

$- A_{\gamma} \mathbf{n}^T_{\gamma} \mathbf{K} \sum_{\alpha} \varrho_{\alpha} \lambda_{\alpha} \mathbf{d}_{ij} \left( \frac{p_{\alpha,j}^t - p^{t}_{\alpha,i}}{\Delta x} + \varrho_{\alpha} \mathbf{g}^T \mathbf{d}_{ij} \right) \sum_{\kappa} X^{\kappa}_{\alpha} \frac{\partial v_{t}}{\partial C^{\kappa}} + V_i \frac{A_{\gamma}}{U_i} \mathbf{d}^T \mathbf{K} \sum_{\alpha} \varrho_{\alpha} \lambda_{\alpha} \mathbf{d}_{ij} \left( \frac{p_{\alpha,j}^t - p^{t}_{\alpha,i}}{\Delta x} + \varrho_{\alpha} \mathbf{g}^T \mathbf{d}_{ij} \right) \sum_{\kappa} X^{\kappa}_{\alpha} \frac{\frac{\partial v_{t,j}}{\partial C^{\kappa}_j}-\frac{\partial v_{t,i}}{\partial C^{\kappa}_i}}{\Delta x}$

This includes a boundary integral and a volume integral, because $\frac{\partial v_{t,i}}{\partial C^{\kappa}_i}$ is not constant. Here, $\mathbf{d}_{ij}$ is the normalized vector connecting the cell centers, and $\mathbf{n}_{\gamma}$ represents the normal of the face $\gamma$ .

Parameters

entries	The Matrix and RHS entries
intersection	Intersection between cell I and J
cellDataI	Data of cell I
first	Flag if pressure field is unknown

◆ getFluxOnBoundary()

template<class TypeTag >

void Dumux::FVPressure2P2C< TypeTag >::getFluxOnBoundary	(	EntryType &	entries,
		const Intersection &	intersection,
		const CellData &	cellDataI,
		const bool	first
	)

inherited

Get flux on Boundary.

for first == true, the flux is calculated in traditional fractional-flow forn as in FVPressure2P. for first == false, the flux thorugh $\gamma$ is calculated via a volume balance formulation

$- A_{\gamma} \mathbf{n}^T_{\gamma} \mathbf{K} \sum_{\alpha} \varrho_{\alpha} \lambda_{\alpha} \mathbf{d}_{ij} \left( \frac{p_{\alpha,j}^t - p^{t}_{\alpha,i}}{\Delta x} + \varrho_{\alpha} \mathbf{g}^T \mathbf{d}_{ij} \right) \sum_{\kappa} \frac{\partial v_{t}}{\partial C^{\kappa}} X^{\kappa}_{\alpha} \;,$

where we skip the volume integral assuming $\frac{\partial v_{t,i}}{\partial C^{\kappa}_i}$ to be constant at the boundary. Here, $\mathbf{d}_{ij}$ is the normalized vector connecting the cell centers, and $\mathbf{n}_{\gamma}$ represents the normal of the face $\gamma$ .

If a Neumann BC is set, the given (mass-)flux is directly multiplied by the volume derivative and inserted.

Parameters

entries	The Matrix and RHS entries
intersection	Intersection between cell I and J
cellDataI	Data of cell I
first	Flag if pressure field is unknown

◆ getMpfaFlux()

template<class TypeTag >

void Dumux::FV2dPressure2P2CAdaptive< TypeTag >::getMpfaFlux	(	const IntersectionIterator &	intersectionIterator,
		const CellData &	cellDataI
	)

Compute flux over an irregular interface using a mpfa method.

A mpfa l-method is applied to calculate fluxes near hanging nodes, using:

$- \sum_{\alpha} \varrho_{\alpha} \lambda_{\alpha} \left( \sum_k \tau_{2k} p^t_{\alpha,k} + \varrho_{\alpha} \sum_k \tau_{2k} \mathbf{g}^T \mathbf{x}_{k} \right) \sum_{\kappa} X^{\kappa}_{\alpha} \frac{\partial v_{t}}{\partial C^{\kappa}} + \frac{ V_i}{U_i} \sum_{\alpha} \varrho_{\alpha} \lambda_{\alpha} \left( \sum_k \tau_{2k} p^t_{\alpha,k} + \varrho_{\alpha} \sum_k \tau_{2k} \mathbf{g}^T \mathbf{x}_{k} \right) \sum_{\kappa} X^{\kappa}_{\alpha} \frac{\frac{\partial v_{t,j}}{\partial C^{\kappa}_j} -\frac{\partial v_{t,i}}{\partial C^{\kappa}_i}}{\Delta x}$

We provide two options: Calculating the flux expressed by twice the flux through the one unique interaction region on the hanging node if one halfedge is stored (eg on boundaries). Or using the second interaction region covering neighboring cells. The contribution in other cells than I or J make it necessary that the matrix and rhs entries are filled up within this function.

Parameters

intersectionIterator	Iterator of the intersection between cell I and J
cellDataI	Data of cell I

get geometrical Info, transmissibility matrix

compute matrix entry: advective fluxes

◆ getSource()

template<class TypeTag >

void Dumux::FVPressure2P2C< TypeTag >::getSource	(	EntryType &	sourceEntry,
		const Element &	elementI,
		const CellData &	cellDataI,
		const bool	first
	)

inherited

Assembles the source term.

for first == true, a source is implemented as in FVPressure2P. for first == false, the source is translated into a volumentric source term:

$V_i \sum_{\kappa} \frac{\partial v_{t}}{\partial C^{\kappa}} q^{\kappa}_i$

.

Parameters

sourceEntry	The Matrix and RHS entries
elementI	The element I
cellDataI	Data of cell I
first	Flag if pressure field is unknown

◆ getStorage()

template<class TypeTag >

void Dumux::FVPressure2P2C< TypeTag >::getStorage	(	EntryType &	storageEntry,
		const Element &	elementI,
		const CellData &	cellDataI,
		const bool	first
	)

inherited

Assembles the storage term.

for first == true, there is no storage contribution. for first == false, the storage term comprises the compressibility (due to a change in pressure from last timestep):

$V_i c_{t,i} \frac{p^t_i - p^{t-\Delta t}_i}{\Delta t}$

and the damped error introduced by the incorrect transport of the last timestep:

$V_i \alpha_r \frac{v_{t} - \phi}{\Delta t}$

. The latter is damped according to Fritz 2011.

storageEntry	The Matrix and RHS entries
elementI	The element I
cellDataI	Data of cell I
first	Flag if pressure field is unknown

postTimeStep Flag indicating method is called from Problem::postTimeStep()

◆ updateMaterialLawsInElement()

template<class TypeTag >

void Dumux::FVPressure2P2C< TypeTag >::updateMaterialLawsInElement	(	const Element &	element,
		bool	postTimeStep
	)

inherited

Updates secondary variables of one cell.

For each element, the secondary variables are updated according to the primary variables. In case the method is called after the Transport, i.e. at the end / post time step, CellData2p2c.reset() resets the volume derivatives for the next time step.

Parameters

element	The element
postTimeStep	Flag indicating if we have just completed a time step

◆ updateVelocity()

template<class TypeTag >

void Dumux::FVPressure< TypeTag >::updateVelocity ( )

inlineinherited

◆ volumeDerivatives()

template<class TypeTag >

void Dumux::FVPressureCompositional< TypeTag >::volumeDerivatives	(	const GlobalPosition &	globalPos,
		const Element &	element
	)

inherited

Partial derivatives of the volumes w.r.t. changes in total concentration and pressure.

This method calculates the volume derivatives via a secant method, where the secants are gained in a pre-computational step via the transport equation and the last TS size. The partial derivatives w.r.t. mass are defined as $\frac{\partial v}{\partial C^{\kappa}} = \frac{\partial V}{\partial m^{\kappa}}$

Parameters

globalPos	The global position of the current element
element	The current element

The 2p Mpfa pressure module, that is only used for the calulation of transmissibility of the second interaction volumes.

◆ updateEstimate_

template<class TypeTag >
