Fluid flow in porous media drives the transport, mixing, and reaction of molecules, particles,
and microorganisms across a wide spectrum of natural and industrial processes. Current …

In many geological systems, the porosity of rock or soil may evolve during mineral
precipitation, a process that controls fluid transport properties. Here, we investigate the use …

Résumé The dynamic response of rocks to thermal, hydrodynamical, mechanical, and
geochemical solicitations is of fundamental interest in several disciplines of geosciences …

This work is concerned, for the first time, with estimating the transverse dispersion coefficient
under non-Darcy laminar flow conditions in porous media using pore-network modeling. The …

Rock heterogeneity plays an important role in solute spreading and mixing in hydrogeologic
systems. Few observations, however, have been made that can spatially resolve these …

Transverse dispersive mixing plays an important role in controlling natural attenuation of
contaminant plumes and the performance of engineered remediation strategies. The extent …

Recent studies have demonstrated that positron emission tomography (PET) is a valuable
tool for in-situ characterization of fluid transport in porous and fractured geologic media at …

Underground fractures serve as flow conduits, and they may produce unwanted migration of
water and other fluids in the subsurface. An example is the migration and leakage of …

Solute transport is important in a variety of applications regarding flow in porous media, such
as contaminant groundwater remediation. Most recent experimental studies on this process …

With the aid of nondestructive microfocus x-ray computed tomography (CT), we performed
three-dimensional (3D) tracer dispersion experiments on randomly unconsolidated packed …
