I have made quasi-2D granular analogs using microfabrication techniques common in microfluidics such as photo- and Soft Lithography. I have performed two kinds of experiments common in multiphase flow problems: drying and immiscible fluid-fluid displacement in granular materials. The granular analogs consisted in arrays of pillars (grains) of uniformly distributed, heterogeneous size. Depending on the experiments, pillars were placed on either a square (for drying experiments) or a triangular ( for immiscible displacement experiments) grid. Experimental results were compared to pore-network models developed in a partner group
