Detailed Description

A fully-implicit multi-phase flow model which assumes immiscibility of the phases.

This model implements multi-phase flow of $M > 0$ immiscible fluids $\alpha$. By default, the standard multi-phase Darcy approach is used to determine the velocity, i.e.

\[ \mathbf{v}_\alpha = - \frac{k_{r\alpha}}{\mu_\alpha} \mathbf{K}\left(\mathbf{grad}\, p_\alpha - \varrho_{\alpha} \mathbf{g} \right) \;, \]

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

template<class TypeTag>
struct FluxModule<TypeTag, TTag::MyProblemTypeTag> { using type = Opm::ForchheimerFluxModule<TypeTag>; };
Opm::ForchheimerFluxModule
Specifies a flux module which uses the Forchheimer relation.
Definition: forchheimerfluxmodule.hh:62

The core of the model is the conservation mass of each component by means of the equation

\[ \frac{\partial\;\phi S_\alpha \rho_\alpha }{\partial t} - \mathrm{div} \left\{ \rho_\alpha \mathbf{v}_\alpha \right\} - q_\alpha = 0 \;. \]

The model uses the following primary variables:

  • The pressure $p_0$ in Pascal of the phase with the lowest index
  • The saturations $S_\alpha$ of the $M - 1$ phases that exhibit the lowest indices
  • The absolute temperature $T$ in Kelvin if energy is conserved via the energy equation
