A critical environmental issue in carbon capture and storage (CCS) is potential CO 2
leakage, which accompanies geochemical reactions with aquifer materials. To investigate …

Numerical analyses are performed to study the fluid dynamic behaviours of the solubility
trapping in the context of CO 2 storage in deep geological formations. Dissolution of CO 2 …

Density-driven convective mixing in porous media can be influenced by the spatial
heterogeneity of the medium. Previous studies using two-dimensional models have shown …

Motivated by processes occurring during sequestration in an underground saline aquifer, we
examine two-dimensional convection in a finite-depth porous medium induced by a solute …

The injection of CO2 into geological formations triggers inherently coupled thermo-hydro-
chemo-mechanical processes. The reservoir pressure and temperature determine the CO2 …

The existing form of the injected CO2 gas is very important to the feasibility and security of
CO2 storage projects in specific geological formations. The residual gas, solubility and …

Reactive transport processes in natural environments often involve many ionic species. The
diffusivities of ionic species vary. Since assigning different diffusivities in the advection …

Chemical reactions can impact mixing in partially miscible stratifications by affecting
buoyancy-driven convection developing when one phase dissolves into the other one in the …

To understand better the evolution of convective finger for Rayleigh convection confined in a
gap with moderate width, we investigated the absorption of CO2 into water experimentally …

This paper presents experimental and theoretical studies of the onset of natural convection
induced by the dissolution of carbon dioxide-nitrogen (CO 2-N 2) mixtures into brine. Using …
