Fluid drainage in erodible porous media
Joanna Schneider, Christopher A. Browne, Malcolm Slutzky +3
Drainage, in which a nonwetting fluid displaces a wetting fluid from a porous medium, is well-studied for media with unchanging solid surfaces. However, many media can be eroded by…
A biophysical threshold for biofilm formation
Jenna A. Ott, Selena Chiu, Daniel B. Amchin +2
Bacteria are ubiquitous in our daily lives, either as motile planktonic cells or as immobilized surface-attached biofilms. These different phenotypic states play key roles in agric…
Influence of confinement on the spreading of bacterial populations
Daniel B. Amchin, Jenna A. Ott, Tapomoy Bhattacharjee +1
The spreading of bacterial populations is central to processes in agriculture, the environment, and medicine. However, existing models of spreading typically focus on cells in unco…
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…
Infection percolation: A dynamic network model of disease spreading
Christopher A. Browne, Daniel B. Amchin, Joanna Schneider +1
Models of disease spreading are critical for predicting infection growth in a population and evaluating public health policies. However, standard models typically represent the dyn…
Chemotactic smoothing of collective migration
Tapomoy Bhattacharjee, Daniel B. Amchin, Ricard Alert +2
Collective migration -- the directed, coordinated motion of many self-propelled agents -- is a fascinating emergent behavior exhibited by active matter that has key functional impl…
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…
