Description

template<class Scalar>
class Dumux::DiffusivityMillingtonQuirk< Scalar >

Millington Quirk

For DiffusivityMillingtonQuirk, the tortuosity coefficient is estimated after Millington and Quirk (1961) [55] by

\[ \tau = \frac{1}{\phi^2} \left(\phi S_\alpha\right)^{7/3}. \]

See also Helmig (1997) [39] [page 129].

static Scalar Dumux::DiffusivityMillingtonQuirk< Scalar >::effectiveDiffusionCoefficient ( const VolumeVariables &  volVars, const int  phaseIdx, const int  compIdxI, const int  compIdxJ  )

inlinestatic

Returns the effective diffusion coefficient ( \(\mathrm{m^2/s}\)) of component \( \kappa \) (index compIdxI) in phase \( \alpha \) computed as \( D^\kappa_{\text{eff},\alpha} = \phi S_\alpha \tau D^\kappa_\alpha \).

Parameters

volVars	The Volume Variables
phaseIdx	the index of the phase
compIdxI	the component index i
compIdxJ	the component index j
