Rayleigh fractionation in high-Rayleigh-number solutal convection in porous media
@article{Wen2018RayleighFI, title={Rayleigh fractionation in high-Rayleigh-number solutal convection in porous media}, author={Baole Wen and Marc A. Hesse}, journal={arXiv: Fluid Dynamics}, year={2018} }
We study the fractionation of two components between a well-mixed gas and a saturated convecting porous layer. Motivated by geological carbon dioxide (CO$_2$) storage we assume that convection is driven only by the dissolved concentration of the first component, while the second acts as a tracer with increased diffusivity. Direct numerical simulations for convection at high Rayleigh numbers reveal that the partitioning of the components, in general, does not follow a Rayleigh fractionation…

The measurements reveal a further enhancement of convection with inclined boundaries, which suggests that sloping formations provide improved sites for CO(2) storage, which may result in an enhanced mass transfer by convection.

This simulation finds that the CO2 concentration field self-organizes as a cellular network structure in the diffusive boundary layer at the top boundary, which identifies various regimes of finger coarsening over time, the existence of a non-equilibrium stationary state, and a universal scaling of three-dimensional convective mixing.
