Relation for the effective diffusion coefficient after Millington and Quirk. More...
#include <dumux/material/fluidmatrixinteractions/diffusivitymillingtonquirk.hh>
For DiffusivityMillingtonQuirk, the tortuosity coefficient is estimated after Millington and Quirk (1961) [millington1961] by   
\[ \tau = \frac{1}{\phi^2} \left(\phi S_\alpha\right)^{7/3}. \]

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