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…
Drag reduction in surfactant-contaminated superhydrophobic channels at high Péclet numbers
Samuel D. Tomlinson, Frédéric Gibou, Paolo Luzzatto-Fegiz +3
Motivated by microfluidic applications, we investigate drag reduction in laminar pressure-driven flows in channels with streamwise-periodic superhydrophobic surfaces (SHSs) contami…
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…
