Experimental Investigation and Pore-Scale Modeling Interpretation of Compound-Specific Transverse Dispersion in Porous Media

Pore-scale dispersion: Bridging the gap between microscopic pore structure and the emerging macroscopic transport behavior

“…On the other hand, subdiffusive behavior in transverse direction with an exponent of 0.8 was reported. Transverse dispersion is of particular importance as it controls biodegradation of organic contaminant plumes to name only one prominent example [21][22][23].…”

Fast laboratory-based micro-computed tomography for pore-scale research: Illustrative experiments and perspectives on the future

“…In groundwater systems, mixing of reactants often limits (bio)chemical reactions [82]. In CO 2 sequestration and enhanced oil recovery, CO 2 dissolved in brine can trigger dissolution and precipitation of minerals in the host rock's pore space, in turn affecting this rock's mechanical and fluid flow properties [43].…”

Observations of 3-D transverse dispersion and dilution in natural consolidated rock by X-ray tomography

“…It is important to keep in mind that transverse dispersion is compound dependent [11,12,40]. In principle, the test is general to any compound of interest, as long as the impact on the local atomic density 520 is sufficient to induce attenuation in the X-ray imagery.…”

“…As many groundwater flows do not often fall within the purely 40 advective-dominated regime, there is a clear need for accurate experimental studies on transverse dispersion.…”
