Simulation and modelling of convective mixing of carbon dioxide in
geological formations
We perform large-scale numerical simulations of convection in 3D porous media at Rayleigh-Darcy numbers up to $Ra=8\times10^4$. To investigate convective mixing of carbon dioxide (CO$_2$) in geological formations, we consider a semi-infinite domain, where the CO$_2$ concentration is constant at top and no flux is prescribed at bottom. Convection begins …
