[case] RelativePermeabilityUdell

A simple relative permeability function proposed by Kent S Udell [39].


\[ k_{\text{rel}}^{\alpha} =\left(S^{\text{eff}}_{\alpha}\right)^{3}\]


  • \(k_{\text{rel}}^{\alpha}\) is relative permeability of phase \(\alpha\)
  • \(S^{\text{eff}}_{\alpha}\) is the effective saturation of phase \(\alpha\)

This class handles the wetting (liquid) phase portion of this relative permeability property, i,e with \(\alpha=L\) 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.
