AB: Two-phase immiscible flows in a lattice-like flow-cell fabricated for studying flow through porous media were analyzed. A computational grid for two-phase viscous fluid flows through the artificial porous medium was developed, and the fluid flows conditions for a range of capillary numbers were evaluated. Time variation of the averaged front movement for various conditions are evaluated the nature of the flow regimes was assessed. The cross-over from Invasion Percolations (IP) flow to Diffusion-Limited Aggregations (DLA) flow in the lattice flow-cell was found. The fractal dimension was calculated and the breakthrough saturations for various Darcy velocities and viscosity ratios were also evaluated. The results from Navier Stokes simulations were compared with the results from Poiseuille/capillary pressure modeling and with previously published results.
