Numerical simulation depicting dynamic infusion of moisture into a porous ceramic tile. This numerical simulation utilized the Richards equation, a commonly employed mathematical model for analyzing water distribution in the vadose zone. COMSOL Multiphysics, a software based on the finite element method, was employed to conduct the simulation.

Numerical simulation illustrating the evolution of arsenic concentration in an adsorptive porous filter cartridge with respect to time [t = 0 day(s) to t = 300 days(s)]. The simulation employs the micro-macro coupling physics based on Whitaker’s closure formulation as used in the mathematically-rigorous volume averaging method.

Simulation of drying of a porous medium using our in-house developed code PORODRY after coupling the inside and outside flows. The simulation uses the pore network model based on Prat’s invasion-percolation algorithm and includes the film effect.

Evolution of partial saturation during mold filling of a car hood simulated by our in-house developed code POREFLOW. It uses our dual-scale model for including the unsaturated-flow physics occurring near the flow front in the woven or stitched fabrics used in resin transfer molding (RTM) for making polymer matrix composites.

Studying the effect of microstructure of a porous medium on wicking of liquids. Simulation was done using Fluent while the random microstructure was generated using GeoDict.

Water Filtration Group:
Led by Prof. Pillai, the Water Filtration Group aims to enhance water filtration processes using porous media. We combine theory, computation, and experimentation to develop innovative methods. Collaborating with global partners, we strive to improve water quality. Learn more on our website.
