The groundwater table fluctuation (GTF) zone is an important medium for the hydrologic
cycle between unsaturated soil and saturated aquifers, which accelerates the migration …

This review provides an overview of concepts and approaches for the quantification of
passive, non-reactive solute mixing in steady uniform porous media flows across scales …

Abstract Underground Hydrogen Storage (UHS) is an attractive technology for large-scale
(TWh) renewable energy storage. To ensure the safety and efficiency of the UHS, it is crucial …

Solute transport in unsaturated porous materials is a complex process, which exhibits some
distinct features differentiating it from transport under saturated conditions. These features …

Low salinity waterflooding has proven to accelerate oil production at core and field scales.
Wettability alteration from a more oil-wetting to a more water-wetting condition has been …

Solute transport in partially-saturated porous media plays a key role in multiple applications
across scales, from the migration of nutrients and contaminants in soils to geological energy …

Macro-scale models of coupled free flow and flow through a permeable medium often lack
the capabilities to account for process-relevant complexities on the pore scale. Direct …

The dynamics of solute dispersion and mixing in unsaturated flows is analyzed from
photobleaching experiments in two‐dimensional porous micromodels. This technique …

Low salinity waterflooding aims to alter rock wettability from oil-wet towards less oil-wet or
water-wet conditions. There is a limited understanding of how wettability alteration impacts …

Solute transport in unsaturated porous media is of interest in many engineering and
environmental applications. The interplay between small-scale, local forces and the porous …
