New Structural Percolation Transition in Fractional Wet 3D‐Porous Media: A Comparative μ‐CT Study

Natural porous media possess spatial heterogeneous (fractional) wettability, which controls the multiphase flow behavior, that is, displacement and trapping. We used mixed hydrophilic (contact angle θ = 0°) and hydrophobic (θ = 100°) 1 mm sands and 1 mm glass beads as model systems for fractional we...
