Transport and removal of a passive tracer in porous media employing surface washing
Georgia Ioannou, Francesco Paolo Cont`o, Merlin A. Etzold +2
This experimental study investigates the dynamics of surface washing to remove a passive tracer from a porous plate by a gravity-driven liquid film across its surface. A disodium f…
Dye Attenuation Without Dye: Quantifying Concentration Fields with Short-wave Infrared Imaging
George T. Fortune, Merlin A. Etzold, Julien R. Landel +1
Dye attenuation, or photometric imaging, is an optical technique commonly used in fluid dynamics to measure tracer concentration fields and fluid thicknesses under the assumption t…
Pattern Formation in Crumpled Hydrogel upon Rapid Dehydration with Acetone
George T. Fortune, Merlin A. Etzold, Julien R. Landel +1
From microactuators to biological tissues, non-porous materials with the ability to strongly expand when in contact with a solvent are ubiquitous. Consequently, the swelling of pol…
Droplet absorption and spreading into thin layers of polymer hydrogels
Merlin A. Etzold, George T. Fortune, Julien R. Landel +1
From biological tissues to layers of paint, macroscopic non-porous materials with the capacity to swell when brought in contact with an appropriate solvent are ubiquitous. Here, we…
Three-dimensional advective--diffusive boundary layers in open channels with parallel and inclined walls
Merlin A. Etzold, Julien R. Landel, Stuart B. Dalziel
We study the steady laminar advective transport of a diffusive passive scalar released at the base of narrow three-dimensional longitudinal open channels with non-absorbing side wa…
