Fluid flow in porous media

We study the physics of multiphase flow and transport phenomena in porous media-of considerable interest for a number of industrial and environmental processes based in the School of Chemical Engineering and Analytical Sciences. Our applications include enhanced oil recovery, CO2 sequestration, disposal of hazardous wastes, water evaporation and infiltration in soil, drying of powders, and salt intrusion in coastal areas. Our interests are mainly focused on the analytical analysis, simulation, measurement and interpretation of various aspects of flow and transport in porous media such as heat and mass transfer, dynamics of miscible and immiscible multiphase flow and interfacial processes in porous media and wetting phenomena.

We combine the results of our experiments obtained by cutting-edge technologies such as x-ray tomography, neutron radiography, and acoustic emission technique with physically-based models to provide better physical understanding of the processes involved in multiphase flow and transport in porous media.

Surface of columns packed with (a) hydrophilic (HI) sand and (b) two hydraulically coupled vertical domains of hydrophobic (HO) and HI sand. The dash line indicates the vertical HI/HO interface. (a) Since evaporation occurs at surface, tracer is deposited there (b) capillary suction between HI and HO grains causes lateral liquid flow from HO to HI sand layer and subsequent evaporation and preferential dye deposition exclusively on HI surface (after Shokri and Or, Journal of Colloid and Interface Science 391, 135–141, 2013).
