Data for the manuscript titled "Solute front shear and coalescence control concentration gradient dynamics in porous micromodel"

Concentration images and data for plots for the manuscript "Solute front shear and coalescence control concentration gradient dynamics in porous micromodel" submitted for publication in Geophysical Research Letters. See the README file for explanations on the data file. Movie captions: Movie S1: Concentration field for the Péclet Pe = 33 experiment. Solid pillars are represented by the gray discs, and the colormap corresponds to the rescaled concentration \(c/c_\mathrm{max}\). The black line represents the solute front, which is the boundary of the continuous \(c/c_\mathrm{max} < 0.5\) region within the porous medium. The x- and y-coordinates of the porous medium length and width (respectively) are rescaled by the average pore diameter \(\lambda\). Movie S2: Concentration gradient field for the Pe = 33 experiment. Solid pillars are represented by the gray discs, and the colormap corresponds to the rescaled gradient \( a \nabla c / c_\mathrm{max}\). The x- and y-coordinates of the porous medium length and width (respectively) are rescaled by the average pore diameter \(\lambda\). Movie S3: Concentration field for the Pe = 1104 experiment. Solid pillars are represented by the gray discs, and the colormap corresponds to the rescaled concentration \(c/c_\mathrm{max}\). The black line represents the solute front, which is the boundary of the continuous \(c/c_\mathrm{max} < 0.5\) region within the porous medium. The x- and y-coordinates of the porous medium length and width (respectively) are rescaled by the average pore diameter \(\lambda\). Movie S4: Concentration gradients field for the Pe = 1104 experiment. Solid pillars are represented by the gray discs, and the colormap corresponds to the rescaled gradient \( a \nabla c / c_\mathrm{max}\). The x- and y-coordinates of the porous medium length and width (respectively) are rescaled by the average pore diameter \(\lambda\).
