Detailed Description

template<int dim>
class FuelCellShop::Equation::ElectronTransportEquation< dim >

This class deals with Electron Transport Equation.

This equation solves a steady-state Ohm's law for electron transport inside the layers.

It is solved with respect to:

$\mathbf{\phi_{s}}$ (electronic_electrical_potential )

where, $\mathbf{\phi_{s}}$ is in Voltages.

This equation can be written as:

$\qquad \mathbf{\nabla} \cdot \left( \hat{\sigma}_{s,eff} \cdot \mathbf{\nabla} \phi_s \right) = 0 \quad \in \quad \Omega$

$\hat{\sigma}_{s,eff}$ is effective electron conductivity tensor [S/cm].

To be well-posed, these equations are equipped with the appropriate boundary conditions. Dirichlet boundary conditions can be mentioned in the subsection "Boundary data". However, some other boundary types require additional information, which can also be provided by the parameter file. We consider several types of boundary conditions:

Galvanostatic (Constant Electron Current Flux): A constant electronic current flux, [A/cm^2] is provided at the boundary. This value is provided using parameter file. If the value is positive, it implies that electronic current flux is leaving out of the boundary, otherwise negative implies entering into the boundary.

$\qquad \mathbf{n} \cdot \left( \hat{\sigma}_{s,eff} \cdot \mathbf{\nabla} \phi_s \right) = C$

These are specified in the parameter file under subsection "Boundary conditions", as a list of comma-separated map-like values.

e.g.

set Constant Electron Current Flux Boundary Conditions = 1: 2 , 4: -0.5

where, boundary_id "1" has constant electron current flux value of 2 [A/cm^2] (leaving out of the boundary) and boundary_id "4" has constant electron current flux value of -0.5 [A/cm^2] (entering into the boundary).

No current flux (Insulated) / Symmetric: A particular case of Neumann boundary condition.

$\qquad \mathbf{n} \cdot \left( \hat{\sigma}_{s,eff} \cdot \mathbf{\nabla} \phi_s \right) = 0$

Remarks

There is no provision to specify boundary indicators for No current flux or Symmetric boundary conditions, as FEM formulation automatically implies a particular boundary is one of these cases, by default.
This class works with the following layer classes only:
- FuelCellShop::Layer::Channel<dim>
- FuelCellShop::Layer::GasDiffusionLayer<dim>
- FuelCellShop::Layer::MicroPorousLayer<dim>
- FuelCellShop::Layer::CatalystLayer<dim>
- FuelCellShop::Layer::SolidLayer<dim>

We solve the whole problem by linearizing the governing equation at each Newton iteration with subsequent CG FEM discretization in space. The class contains the necessary class members to add the necessary contributions to cell_matrix and cell_residual to the governing equations used to analyze electron transport by Ohm's law,

Usage Details:

* // Creating Equation object (in Application Header file)
* FuelCellShop::Equation::ElectronTransportEquation<dim> electron_transport;
*
* // Declare parameters in application
* electron_transport.declare_parameters(param);
*
* // Initialize in application
* electron_transport.initialize(param);
*
* // Create a temporary vector in the application for storing couplings_map from all the equation used in the application.
* std::vector<couplings_map> tmp;
* ... // other equations
* tmp.push_back( electron_transport.get_internal_cell_couplings() );
*
* // Look at ReactionSourceTerms class here, if source terms due to electrochemical reaction are to be considered.
* // Making cell couplings using SystemManagement object created in the application
* system_management.make_cell_couplings(tmp);
*
* // cell_matrix in application
* // Do a check against layer and it should match with the layers currently working for this equation class.
* // for eg: CGDL is FuelCellShop::Layer::DesignFibrousGDL<dim> object.
* electron_transport.assemble_cell_matrix(cell_matrices, cell_info, &CGDL);
*
* // cell_residual in application
* electron_transport.assemble_cell_residual(cell_vector, cell_info, &CGDL);
* 

Note: This class doesn't assemble for reaction source terms; that is taken care off by ReactionSourceTerms class. Please read the documentation of ReactionSourceTerms class, for additional methods to be implemented in the application.

Warning: If current source terms due to reaction are being considered, it's very important to use adjust_internal_cell_couplings member function of ReactionSourceTerms class, before using make_cell_couplings of SystemManagement at the application level.

TODO Old Boundary conditions including Dirichlet Boundary Conditions and Constant Electron Current Flux Boundary Conditions are supposed to be replaced with the new subsections, see TO BE REMOVED comments in .cc file.
