WebA simple computer model of viscous fingering in a porous medium is presented, together with experimental results for fingering of oil into glycerine in etched-glass networks. The model treats the medium as a square lattice of connected tubes with randomly chosen … WebMar 30, 2024 · Our results suggest that the. gradual reduction of pore sizes act to restrain viscous fingering for a predictable range of flow conditions (as anticipated by gradient. percolation theory). The study provide insights into ways for suppressing unwanted interfacial instabilities in porous media, and provides design principles for new …
