Detailed Description
Immiscible Multi-Phase Model.
This model implements multi-phase flow of 
immiscible fluids 
. By default, the standard multi-phase Darcy approach is used to determine the velocity, i.e.
![\[ \mathbf{v}_\alpha = - \frac{k_{r\alpha}}{\mu_\alpha} \mathbf{K}\left(\mathbf{grad}\, p_\alpha - \varrho_{\alpha} \mathbf{g} \right) \;, \]](form_58.png)
although the actual approach which is used can be specified via the FluxModule property. For example, the velocity model can by changed to the Forchheimer approach by
SET_TYPE_PROP(MyProblemTypeTag, FluxModule, Ewoms::ForchheimerFluxModule<TypeTag>);
The core of the model is the conservation mass of each component by means of the equation
![\[ \frac{\partial\;\phi S_\alpha \rho_\alpha }{\partial t} - \mathrm{div} \left\{ \rho_\alpha \mathbf{v}_\alpha \right\} - q_\alpha = 0 \;. \]](form_59.png)
The model uses the following primary variables:
- The pressure
in Pascal of the phase with the lowest index - The saturations
of the 
phases that exhibit the lowest indices - The absolute temperature
in Kelvin if energy is conserved via the energy equation
