Detailed Description

template<class TypeTag>
class Opm::DarcyExtensiveQuantities< TypeTag >

Provides the Darcy flux module

The commonly used Darcy relation looses its validity for Reynolds numbers $ Re < 1$ . If one encounters flow velocities in porous media above this threshold, the Forchheimer approach can be used.

The Darcy equation is given by the following relation:

$\vec{v}_\alpha = \left( \nabla p_\alpha - \rho_\alpha \vec{g}\right) \frac{\mu_\alpha}{k_{r,\alpha} K}$
