Effect of Pore-Scale Mineral Spatial Heterogeneity on Chemically Induced Alterations of Fractured Rock: A Lattice Boltzmann Study

Figure 12

Concentration (mol/L) of species A_(aq) when (a) Pe = 26 and Da = 20 and (b) Pe = 26 and Da = 10. In both (a) and (b), porosity (after dissolution) is near 0.52 but permeability (after dissolution) is 1.39 × 10⁻⁹ m² for (a) and 1.43 × 10⁻⁹ m² for (b). The nonreactive minerals are illustrated in light gray. The areas showing a zero concentration of species A_(aq) are representing reactive minerals.
