Detailed Description

Internal class to manage the direct and derived quantities needed to formulate the fluid transport system.

Note: This class elides off-diagonal elements of the phase mobility Jacobian, $(\partial_{s_\beta} \lambda_\alpha)_{\alpha\beta}$ . These elements are assumed to be strictly equal to zero. In other words, the relative permeability of phase $\alpha$ is assumed to depend only on the saturation of phase $\alpha$ . This convention allows storing only the two diagonals of the mobility Jacobian per grid cell.

The static gravity term is the scalar value

$\Delta G_i = \mathsf{T}_f\, \vec{g}\cdot(\Bar{x}_f - \Bar{x}_c)$

in which i is the half face index corresponding to the cell-face pair (f,c) and $\mathsf{T}_f$ is the absolute (bacground) two-point transmissibility of face f.

The fluid transport problem is formulated in terms of saturation changes, $\Delta s$ , per cell. These changes are the primary degrees of freedom in this model.

Capillary pressures are defined by the fluid model, but usually correspond to $p_w - p_n$ (e.g., $p_\mathit{oil} - p_\mathit{water}$ ).
