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

Figure 31

Steady-state concentrations, obtained by analytical (contour and solid lines) and LB (dashed lines) methods, for a single species diffusing through the left boundary of a square domain and reacting at the top boundary according to a first-order reaction while other boundaries are zero concentration gradients.
