Description

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

Millington Quirk

For DiffusivityMillingtonQuirk, the tortuosity coefficient is estimated after Millington and Quirk (1961) [58] by

$$\tau =\frac{1}{{\varphi }^2}{\left(\varphi S_{\alpha }\right)}^{7/3}.$$

See also Helmig (1997) [41] [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 ( ${\mathrm{m}}^2/\mathrm{s}$) of component $\kappa$ (index compIdxI) in phase $\alpha$ computed as $D_{\text{eff},\alpha }^{\kappa }=\varphi S_{\alpha }\tau D_{\alpha }^{\kappa }$.

Parameters

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