Abstract
The ambiguous dynamics associated with heat and mass transfer of invading carbon dioxide in sub-critical
and supercritical states, as well as the response of pore-scale resident fluids, play a key role in understanding
CO
2 capture and storage (CCUS) and the corresponding phase equilibrium mechanisms. To this end, this
paper reveals the transport mechanisms of invading supercritical carbon dioxide (sCO
2) in polluted
micromodels using a variant of Lattice-Boltzmann Color Fluid model and descriptive experimental data. The
breakthrough time is evaluated by characterizing the displacement velocity, the capillary to pressuredifference ratio, and the transient heat and mass diffusion at a series of micromodels with scaling porethroats. Wet micromodels are also processed to establish a reference database towards a natural extension
to saline aquifers. The prime recorded sub-regimes are remarkably categorized as oscillatory while the
interfacial velocity of sCO
2/pollutant is jumping into oscillatory magnitudes. The transient saturation of sCO
2
would be significantly accelerated with decreasing pore-throats, demonstrating increased invasion
efficiency. Accordingly, a special model would be established to account for the transport mechanisms of
invading sCO
2 towards efficient geological sequestration.
