Description

template<class TypeTag>
class Dumux::FVPressure2P2CMultiPhysics< TypeTag >

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

Provides a Finite Volume implementation for the pressure equation of a gas-liquid 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.

The model domain is automatically divided in a single-phase and a two-phase domain. The full 2p2c model is only evaluated within the two-phase subdomain, whereas a single-phase transport model is computed in the rest of the domain.

function which assembles the system of equations to be solved

for first == true, this function assembles the matrix and right hand side for the solution of the pressure field in the same way as in the class FVPressure2P. for first == false, the approach is changed to

\[-\frac{\partial V}{\partial p} \frac{\partial p}{\partial t}+\sum_{\kappa}\frac{\partial V}{\partial m^{\kappa}}\nabla\cdot \left(\sum_{\alpha}C_{\alpha}^{\kappa}\mathbf{v}_{\alpha}\right) =\sum_{\kappa}\frac{\partial V}{\partial m^{\kappa}}q^{\kappa} \]

◆ get1pFlux()

template<class TypeTag >

void Dumux::FVPressure2P2CMultiPhysics< TypeTag >::get1pFlux	(	EntryType &	entries,
		const Intersection &	intersection,
		const CellData &	cellDataI
	)

The compositional single-phase flux in the multiphysics framework.

If only single-phase conditions are encountered, the flux expression simplifies to (written for the case where the wetting phase is only present):

\[ A_{\gamma} \mathbf{n}_{\gamma}^T \mathbf{K} \lambda_w \mathbf{d}_{ij} \left( \frac{p_{w,j}^t - p^{t}_{w,i}}{\Delta x} + \varrho_{w} \mathbf{g}^T \mathbf{d}_{ij} \right) . \]

Parameters

entries	The Matrix and RHS entries
intersection	Intersection between cell I and J
cellDataI	Data of cell I

◆ get1pFluxOnBoundary()

template<class TypeTag >

void Dumux::FVPressure2P2CMultiPhysics< TypeTag >::get1pFluxOnBoundary	(	EntryType &	entries,
		const Intersection &	intersection,
		const CellData &	cellDataI
	)

The compositional single-phase flux in the multiphysics framework.

If only single-phase conditions are encountered, the flux expression simplifies to (written for the case where the wetting phase is only present):

\[ A_{\gamma} \mathbf{n}_{\gamma}^T \mathbf{K} \varrho_w \lambda_w \mathbf{d}_{i-Boundary} \left( \frac{p_{w,Boundary}^t - p^{t}_{w,i}}{\Delta x} + \varrho_{w} \mathbf{g}^T \mathbf{d}_{i-Boundary} \right) . \]

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

◆ get1pSource()

template<class TypeTag >

void Dumux::FVPressure2P2CMultiPhysics< TypeTag >::get1pSource	(	EntryType &	sourceEntry,
		const Element &	elementI,
		const CellData &	cellDataI
	)

Assembles the source term.

The source is translated into a volumentric source term:

\[ V_i \sum_{\kappa} \frac{1}{\varrho} q^{\kappa}_i \; , \]

because under singlephase conditions

\[ \frac{\partial v_{t}}{\partial C^{\kappa}} \approx \frac{1}{\varrho} \]

.

Parameters

sourceEntry	The Matrix and RHS entries
elementI	The element I
cellDataI	Data of cell I

◆ get1pStorage()

template<class TypeTag >

void Dumux::FVPressure2P2CMultiPhysics< TypeTag >::get1pStorage	(	EntryType &	storageEntry,
		const Element &	elementI,
		CellData &	cellDataI
	)

Assembles the storage term for a 1p cell in a multiphysics framework.

The storage term comprises the (single-phase) compressibility (due to a change in pressure from last timestep):

\[ V_i c_{i} \frac{p^t_i - p^{t-\Delta t}_i}{\Delta t} \]

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.

Parameters

storageEntry	The Matrix and RHS entries
elementI	The element I
cellDataI	Data of cell I

◆ 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.

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

	)

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

		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

		CellData &	cellData,
		bool	postTimeStep
	)

updates secondary variables of one single phase cell

For each element, the secondary variables are updated according to the primary variables. Only a simple flash calulation has to be carried out, as phase distribution is already known: single-phase.

Parameters

elementI	The element
cellData	The cell data of the current element
postTimeStep	Flag indicating if we have just completed a time step

◆ updateMaterialLaws()

template<class TypeTag >

void Dumux::FVPressure2P2CMultiPhysics< TypeTag >::updateMaterialLaws ( bool postTimeStep = false )

constitutive functions are updated once if new concentrations are calculated and stored in the variables container

In contrast to the standard sequential 2p2c model ( FVPressure2P2C<TypeTag>::updateMaterialLaws() ), this method also holds routines to adapt the subdomain. The subdomain indicates weather we are in 1p domain (value = 1) or in the two phase subdomain (value = 2). Note that the type of flash, i.e. the type of FluidState (FS), present in each cell does not have to coincide with the subdomain. If a cell will be simple and was complex, a complex FS is available, so next time step will use this complex FS, but updateMaterialLaw afterwards will finally transform that to simple FS.

Parameters

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
