Challenges in the Application of Fractional Derivative Models in Capturing Solute Transport in Porous Media: Darcy-Scale Fractional Dispersion and the Influence of Medium Properties

Figure 5

Best-fit of BTCs (solid lines) using model (4) versus the laboratory measurement (symbols), assuming that the subdiffusion is advection dominated, for glass beads with sizes 1 + 0.2 mm (a) and 0.4 + 0.2 mm (b). The dashed line is the best-fit Gaussian solution, shown for comparison. See text for the meaning and model parameters for “fit 1” and “fit 2.”
