Query: A multiscale modeling study for the convective mass transfer in a
  subsurface aquifer   Quantitative and realistic computer simulations of mass transfer associated
with CO2 disposal in subsurface aquifers is a challenging endeavor. This
article has proposed a novel and efficient multiscale modeling framework, and
has examined its potential to study the pen- etrative mass transfer in a CO2
plume that migrates in an aquifer. Nu- merical simulations indicate that the
migration of the injected CO2 enhances the vorticity generation, and the
dissolution of CO2 has a strong effect on the natural convection mass transfer.
The vorticity decays with the increase of the porosity. The time scale of the
vertical migration of a CO2 plume is strongly dependent on the rate of CO2
dissolution. Comparisons confirm the near optimal performance of the proposed
multiscale model. These primary results with an idealized computational model
of the CO2 migration in an aquifer brings the potential of the proposed
multiscale model to the field of heat and mass transfer in the geoscience.
