PorousFlowRelativePermeabilityBW

Broadbridge-White form of relative permeability

The relative permeability of the phase is $var element = document.getElementById("moose-equation-a224fdb1-ee4e-4075-bd70-0b9bc0be74ec");katex.render("k_{\\mathrm{r}} = K_{n} + \\frac{K_{s} - K_{n}}{(c - 1)(c - S_{\\mathrm{eff}})}S_{\\mathrm{eff}}^{2},", element, {displayMode:true,throwOnError:false});$ where the effective saturation is $var element = document.getElementById("moose-equation-1b99286c-544b-4f5b-9f79-78fddc975932");katex.render("S_{\\mathrm{eff}}(S) = \\frac{S - S_{\\mathrm{res}}^{\\beta}}{1 - \\sum_{\\beta\'}S_{\\mathrm{res}}^{\\beta\'}}.", element, {displayMode:true,throwOnError:false});$

Input Parameters

CBW's C parameter. Must be > 1. Typical value would be 1.05.
