(a) Three-stage (i.e., stages I, II, and III) temporal evolution of total discharge, , and non-wetting fluid discharge, , for three values and . (b) Temporal evolution of distribution (simulation time is normalized to the maximum lattice time of ) as a function of porous medium conductivity for null (middle panel) and non-null (bottom panel) hydraulic gradients with and . The top panel shows the histogram of the normalized velocity. (c) Droplet evolution at two different times (early and later times at stage II) during spinodal decomposition for , , and .
