Description

template<class TypeTag>
class Dumux::FVPressure2P2C< 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 pressure base class FVPressure assembles the matrix and right-hand-side vector and solves for the pressure vector, whereas this class provides the actual entries for the matrix and RHS vector. The partial derivatives of the actual fluid volume \( v_{total} \) are gained by using a secant method.

void Dumux::FVPressureCompositional< TypeTag >::addOutputVtkFields ( MultiWriter &  writer)
inlineinherited

Write data files.

Adds pressure-related quantities, including numerical things such as the volume Error entering the pressure equation. Verobosity of the output can be triggered by the property / parameter VtkOutputLevel, with 0 putting out only primary variables and 4 being very verbose.

Parameters
writerThe output writer (usually a VTKMultiWriter object)

◆ assemble()

template<class TypeTag >
void Dumux::FVPressure< TypeTag >::assemble ( bool  first)
protectedinherited

Function which assembles the system of equations to be solved.

This function assembles the Matrix and the right hand side (RHS) vector to solve for a pressure field with a Finite-Volume (FV) discretization. Implementations of this base class have to provide the methods getSource(), getStorage(), getFlux() and getFluxOnBoundary() if the assemble() method is called!

Parameters
firstIndicates if function is called at the initialization step or during the simulation (If first is true, no pressure field of previous iterations is required)

◆ calculateVelocity()

template<class TypeTag >
void Dumux::FVPressure< TypeTag >::calculateVelocity ( )
inlineinherited

◆ deserializeEntity()

const Element &  element 
)
inlineinherited

Function for deserialization of the pressure field.

Function needed for restart option. Reads the pressure of a grid element from a restart file.

Parameters
instreamStream from the restart file.
elementGrid element

◆ getFlux()

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

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
entriesThe Matrix and RHS entries
intersectionIntersection between cell I and J
cellDataIData of cell I
firstFlag 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 
)

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
entriesThe Matrix and RHS entries
intersectionIntersection between cell I and J
cellDataIData of cell I
firstFlag if pressure field is unknown

◆ getSource()

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

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
sourceEntryThe Matrix and RHS entries
elementIThe element I
cellDataIData of cell I
firstFlag 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 
)

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.

Parameters
storageEntryThe Matrix and RHS entries
elementIThe element I
cellDataIData of cell I
firstFlag if pressure field is unknown
