The Division of Fluid Dynamics meeting celebrates the interface of science and art through the Gallery of Fluid Motion, a yearly showcase of visually stunning fluids research. A panel of judges assessed this year’s entries, selecting the top video and poster submissions that will be published in Physical Review Fluids in 2019. The poster winners of the 2018 Milton van Dyke Award and the APS/DFD Gallery of Fluid Motion Award listed here, along with the video winners, can be viewed at the Gallery of Fluid Motion website.
Viscoelastic Fishbones (P0045) by Bavand Keshavarz, Michela Geri, and Gareth McKinley, Massachusetts Institute of Technology. Colliding fluid jets form a blurred liquid fan, but when illuminated with an electric spark flash the pattern is frozen in time.
Delta Wing Vortices (P0020) by Sarah Morris and C. H. K. Williamson, Cornell University. Although seemingly simple, counter-rotating vortex pairs created by a wing surface moving through a fluid can produce complex three-dimensional dynamics.
Whiskey Webs (P0002) by Stuart Williams, Martin Brown, and Adam Carrithers, University of Louisville. Bourbon whiskey is a colloid and as the ethanol evaporates, maturation-derived polymers and surfactants cause erratic fluid motion, leading to unique deposited structures.
Liquid Deposition through Evaporation (P0056) by Asher Mouat, Clay Wood, Justin Pye, and Justin Burton, Emory University. As binary liquid mixtures evaporate, they generate spreading patterns and leave behind structures that can be tuned by surface treatment.
Painting Fluid Motion (P0004) by Maxime Bassenne, Andrew Banko, Sadaf Sobhani, Stanford University. In 1982, Milton van Dyke published An Album of Fluid Motion, a unique collection of over 300 black-and-white photographs illustrating a diverse set of fluid phenomena. Neural networks can combine the content of these photographs with the style of a timeless painting.
