Abstract

In this work, the 2D flow of CO2 injected into a water-saturated homogeneous porous media was numerically investigated using the pseudopotential multiphase Lattice Boltzmann Method (LBM). Firstly, the transient flow is analyzed using a uniform inlet velocity boundary condition to trigger the natural frequency of instabilities developed downstream in the interstitial passages of the pore structure under study. Then, the pulsatile injection of CO2, maintaining the average inlet velocity but varying the forcing frequency through values near and far from the natural frequency, was studied to determine the effect on the penetration of CO2. Results demonstrated that a pulsatile CO2 injection might effectively enhance carbon dioxide sequestration in aquifers when a characteristic
natural frequency associated with the underground porous structure is known.
