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…
