Description
Mixing and reaction in porous and fractured media govern a wide range of natural and engineering processes, including carbon mineralization, cave formation, geothermal energy production, contaminant transport, and microfluidics. Subsurface systems often feature fractures and conduits that serve as highways for fluid flow. Typical flow velocities in these systems are high enough to induce inertial flows, resulting in complex flow topologies. However, due to the common perception that porous media and microchannel flows are slow, the effects of fluid inertia are often overlooked in studies of mixing and reaction. In this talk, I will present our recent findings, derived from microfluidics experiments and numerical simulations, that reveal how fluid inertia fundamentally transforms reactive transport processes, including mixing-induced chemical reactions as well as mineral dissolution and precipitation. Lastly, I will illustrate how these insights can inspire solutions to critical challenges such as carbon mineralization and fracture sealing.
