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

Figure 26

Velocity profile (m/s) for cases with (a) mixed and (b) banded structures when Pe = 2.6 for a multispecies case. In both (a) and (b), porosity (after dissolution) is near 0.47 but permeability (after dissolution) is 1.58 × 10⁻⁹ m² for (a) and 1.43 × 10⁻⁹ m² for (b).
