Richards multi-component flow. More...

Description

Base class for all models which use the Richards, n-component fully implicit model.

This extension of Richards' equation, allows for the wetting phase to consist of multiple components:

\begin{eqnarray*} && \frac{\partial (\sum_w \varrho_w X_w^\kappa \phi S_w )} {\partial t} - \sum_w \nabla \cdot \left\{ \varrho_w X_w^\kappa \frac{k_{rw}}{\mu_w} \mathbf{K} (\nabla p_w - \varrho_{w} \mathbf{g}) \right\} \nonumber \\ \nonumber \\ &-& \sum_w \nabla \cdot \left\{{\bf D_{w, pm}^\kappa} \varrho_{w} \nabla X^\kappa_{w} \right\} - \sum_w q_w^\kappa = 0 \qquad \kappa \in \{w, a,\cdots \} \, , w \in \{w, g\}, \end{eqnarray*}
