[case] NonWettingPhaseVanGenuchten

van Genuchten model: non-wetting phase

\[k{rel}= (1 - S_e)^{1/3} (1 - S_e^{1/m})^{2m}\]

with

\[S_e=\frac{S^w-S_r}{S^w_{\mbox{max}}-S^w_r}\]

where

\begin{eqnarray*} &S^w_r& \mbox{residual saturation of wetting phase,}\\ &S^w_{\mbox{max}}& \mbox{maximum saturation of wetting phase,}\\ &m(<=1) & \mbox{ exponent.}\\ \end{eqnarray*}

Note:

\[m=1/(1-n)\]
