Viscous fingering effect

In miscible system, viscous fluid is triggered by viscous force due to the differences in fluid concentration, also the molecular diffusion and mechanical dispersion of the fluid system.

Spinodal decomposition & capillary bridge

Phase-field models are becoming increasingly popular in hydrodynamics for modeling multi-phase fluid flow below Darcy scale. Instead of sharp interfaces, phase transitions appear as diffuse finite-thickness transition regions.

Miscible flow through heterogeneous porous media

Energy applications: enhanced oil recovery, oil and gas production, CO2 sequestration.
Environmental applications: remediation of contaminated groundwater sites.
Bio-medical applications: cell motility, swelling of tissue (intestinal edema).
Processes in porous media are naturally complex as they relate to various engineering disciplines and span multiple space and time scales.   Our research group Computational Optimization and Modeling of Porous Media (COMP-M) develops state of the art algorithms for modeling and optimizing physical phenomena occurring in porous media.
