A simple relative permeability function proposed by Kent S GeneralizedPower [41].
Definition:
k_{\text{rel}} =\text{multiplier} \left(1-S^{\text{eff}}\right)^{\text{exponent}}
where S^{\text{eff}} is the effective saturation of the non-wetting phase.
This class handles the non-wetting (gas) phase portion of this relative permeability property for the relative permeability function.
This property must be a medium property, it computes the permeability reduction due to saturation as function of capillary pressure.
