Microscopic Particle Image Velocimetry Analysis of Multiphase Flow in a Porous Media Micromodel.

ABSTRACT: Pore-scale oil displacement behavior was investigated in a porous media micromodel using microscopic particle image velocimetry (μPIV). Porous media micromodels consisting of an ordered square array of cylindrical pillars with 50 and 70% porosities were fabricated with photolithography. The oil displacement was performed with the injection of water at flow rates of 37.5, 75, and 150 μL/h. These flow rates correspond to Reynolds number of 1.1 × 10^-2, 2.2 × 10^-2, and 4.4 × 10^-2, respectively in the 50% porous channel, and 1.84 × 10^-3, 3.69 × 10^-3, and 7.38 × 10^-3, respectively in the 70% porous channel. The capillary numbers for these flow rates are 2.18 × 10^-5, 4.36 × 10^-5, and 8.72 × 10^-5, re
