Permeability modeling
WebJan 19, 2016 · The permeability of one region is one-fourth that of the other region. The relative permeabilities are given by Eqs. 2 and 3 with λ = 2 and with Sor = Sgc = 0.20. Corey and Rathjens [3] noted two consequences of laminations: bumps in the relative permeability relationships and a shifting of the critical gas saturation. WebSep 27, 2024 · We can use the postprocessing tools within COMSOL Multiphysics to extract the porosity and compute the permeability by using Darcy’s law. The dimensions of the whole geometry are 640 × 320 μm (and the channel width in the pore spaces is even narrower), so we know the characteristic length scale, L, is small.
