The problem of convection in a fluid-saturated porous medium is reviewed with a focus on
'vigorous' convective flow, when the driving buoyancy forces are large relative to any …

Convection-driven porous media flows are common in industrial processes and in nature.
The multiscale and multiphase character of these systems and the inherent nonlinear flow …

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 present study investigates the behavior of multi-layer Rayleigh–Taylor instability (RTI)
and enstrophy transport in the flow using a three-dimensional computational framework. The …

Density-driven convection, which can accelerate the dissolution rate of carbon dioxide
(CO2) in resident brine, is critical for the long-term fate of the injected CO2 permanence and …

Investigating Rayleigh–Bénard convection, its onset, and its effect on mass transfer are
crucial for understanding the effective dissolution processes between carbon-dioxide (CO 2) …

We consider the process of convective dissolution in a homogeneous and isotropic porous
medium. The flow is unstable due to the presence of a solute that induces a density …

Investigations of fluid instability and density-driven convection in soils and rocks are
motivated by both natural phenomena giving rise to ecological problems, and human …

We assess experimentally the scaling laws that characterize the mixing region produced by
the Rayleigh-Taylor instability in a confined porous medium. In particular, we wish to assess …

We report experiments of fingering asymmetry in Rayleigh-Taylor (RT) mixing at an
extremely large viscosity ratio (M≈ 5× 10 5) and Rayleigh numbers [Ra∼ 10 5–(3× 10 6)] …
