Explore fluid-fluid displacement patterns in porous media through this 44-minute lecture by Assistant Professor Benzhong (Robin) Zhao from McMaster University. Delve into two recent studies: the first examining reactive fluid displacement in a Hele-Shaw cell, where precipitate formation leads to intricate fingering patterns, and the second investigating the impact of heterogeneous wettability on two-phase flow in porous media. Learn about the development of an advection-diffusion-reaction-deposition model capturing observed patterns and precipitation rates. Discover how wettability alteration dramatically affects macroscopic displacement patterns and oil trapping in mixed-wet porous media. Gain insights into pore-scale simulations and dynamic pore-network modeling that explain counterintuitive observations in fluid-fluid displacement processes.
