This research lab aims to conduct high-quality research in diverse areas of flow and transport in porous media. The main thrust is on the theoretical and computational modeling of flow and transport processes backed by rigorous experimental validation.
1- In collaboration with the Advanced Cement Laboratory at UWM, we conducted a study on modeling the infusion of water into ceramic materials, both with and without hydrophobic coatings on it. Our research findings have been published in Scientific Reports – Nature., Link to the article. .
2- Professor Pillai was invited in June 2023 to join as an editorial board member of the newly created journal ‘Interpore Journal’, which he accepted. This journal is fully owned and operated by the most prominent international society for research in porous media, the ‘InterPore’.
4- Aman Raizada, who completed MS under Prof. Pillai, was accepted into the Ph.D. program of Stanford in 2021
5- Prof. Krishna M. Pillai, a prominent researcher in the field of “Flow and Transport through Porous Media,” has been nominated to be among the top 2% of scientists worldwide.59 UWM scientists ranked in top 2% globally
6- Amin Zarandi, an ex-PhD student of Prof. Pillai, received the Academic Excellence Award 2019 from UWM College of Engineering and Applied Sciences
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.
