UChicago physicists achieve breakthrough in vortex dynamics with 3D printing and red Sharpie

A team of physicists from the University of Chicago recently achieved a breakthrough in the field of experimental vortex dynamics. Using 3D printed hydrofoils to create thin-core vortices, and with the lucky help of a red Sharpie marker, the team was able to capture measurements of total helicity, a fundamental property of fluid flow, for the first time. Total helicity, described as “the measure of when two vortex rings intertwine,” had prior to this point been impossible to measure in a laboratory. Now, however, thanks to a happy accident caused by a red marker, UChicago has accomplished the impossible. […]
