We consider experimentally the instability and mass transport of flow in a Hele-Shaw
geometry. In an initially stable configuration, a lighter fluid (water) is located over a heavier …

We experimentally examine dissolution-generated, density-driven convection with an
inclined boundary in both a Hele-Shaw cell and in a porous medium. The convection …

We report numerical simulations related to two-fluid flow in porous media. We assume that
Darcy's law holds for the flow of each of the two fluids, one of which we are injecting into the …

The scalings of the Rayleigh-Taylor instability are studied numerically for porous media
flows when the denser fluid lying on top of the less dense one is also much more viscous …

The influence of chemical reactions on the hydrodynamical fingering instability is analyzed
for miscible systems in porous media. Using a realistic reaction scheme, it is shown that the …

Injection of carbon dioxide (CO 2) into saline aquifers confined by low-permeability cap rock
will result in a layer of CO 2 overlying the brine. Dissolution of CO 2 into the brine increases …

Dissolution of CO 2 into saline aquifers can lead to the development of buoyancy-driven
convection in the brine which enhances the efficiency of CO 2 transfer. We analyze here …

We are generally interested in viscously driven instabilities in heterogeneous porous media
for a variety of applications, including chromatographic separations and the passage of …

We experimentally demonstrate that a precipitation reaction at the miscible interface
between two reactive solutions can trigger a hydrodynamic instability due to the buildup of a …

Viscous fingering is a flow instability that is induced at the displacement front when a less-
viscous fluid (LVF) displaces a more-viscous fluid (MVF). Because of the opaque nature of …
