Forced Imbibition in Stratified Porous Media: Fluid Dynamics and Breakthrough Saturation
Nancy B. Lu, Daniel B. Amchin, Sujit S. Datta
Imbibition, the displacement of a nonwetting fluid by a wetting fluid, plays a central role in diverse energy, environmental, and industrial processes. While this process is typica…
Under pressure: Hydrogel swelling in a granular medium
Jean-François Louf, Nancy B. Lu, Margaret G. O'Connell +2
Hydrogels hold promise in agriculture as reservoirs of water in dry soil, potentially alleviating the burden of irrigation. However, confinement in soil can markedly reduce the abi…
Forced Imbibition in Stratified Porous Media
Nancy B. Lu, Amir A. Pahlavan, Christopher A. Browne +3
Imbibition plays a central role in diverse energy, environmental, and industrial processes. In many cases, the medium has multiple parallel strata of different permeabilities; howe…
Controlling capillary fingering using pore size gradients in disordered media
Nancy B. Lu, Christopher A. Browne, Daniel B. Amchin +2
Capillary fingering is a displacement process that can occur when a non-wetting fluid displaces a wetting fluid from a homogeneous disordered porous medium. Here, we investigate ho…
Crack formation and self-closing in shrinkable, granular packings
H. Jeremy Cho, Nancy B. Lu, Michael P. Howard +2
Many clays, soils, biological tissues, foods, and coatings are shrinkable, granular materials: they are composed of packed, hydrated grains that shrink when dried. In many cases, t…
