class Ewoms::ForchheimerBaseProblem< TypeTag >

Provides the defaults for the parameters required by the Forchheimer velocity approach.

Scalar Ewoms::ForchheimerBaseProblem< TypeTag >::ergunCoefficient ( const Context &context  OPM_UNUSED,
unsigned spaceIdx  OPM_UNUSED,
unsigned timeIdx  OPM_UNUSED 
) const
inline

Returns the Ergun coefficient.

The Ergun coefficient is a measure how much the velocity is reduced by turbolence. It is a quantity that does not depend on the fluid phase but only on the porous medium in question. A value of 0 means that the velocity is not influenced by turbolence.

Evaluation Ewoms::ForchheimerBaseProblem< TypeTag >::mobilityPassabilityRatio ( Context &  context,
unsigned  spaceIdx,
unsigned  timeIdx,
unsigned  phaseIdx 
) const
inline

Returns the ratio between the phase mobility $k_{r,\alpha}$ and its passability $\eta_{r,\alpha}$ for a given fluid phase $\alpha$.

The passability coefficient specifies the influence of the other fluid phases on the turbolent behaviour of a given fluid phase. By default it is equal to the relative permeability. The mobility to passability ratio is the inverse of phase' the viscosity.
