Vigorous convection in porous media

DR Hewitt - Proceedings of the Royal Society A, 2020 - royalsocietypublishing.org
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 …

Solutal convection in porous media: Comparison between boundary conditions of constant concentration and constant flux

MA Amooie, MR Soltanian, J Moortgat - Physical Review E, 2018 - APS
We numerically examine solutal convection in porous media, driven by the dissolution of
carbon dioxide (CO 2) into water—an effective mechanism for CO 2 storage in saline …

Effect of dispersion on solutal convection in porous media

Y Liang, B Wen, MA Hesse… - Geophysical Research …, 2018 - Wiley Online Library
Solutal convection in porous media is thought to be controlled by the molecular Rayleigh
number, R am, the ratio of the buoyant driving force over diffusive dissipation. The mass flux …

Scalings of Rayleigh-Taylor instability at large viscosity contrasts in porous media

N Sabet, H Hassanzadeh, A De Wit, J Abedi - Physical review letters, 2021 - APS
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 …

Chemo-hydrodynamic patterns in porous media

A De Wit - … Transactions of the Royal Society A …, 2016 - royalsocietypublishing.org
Chemical reactions can interplay with hydrodynamic flows to generate chemo-hydrodynamic
