2009 Video Gallery
The Division of Fluid Dynamics exists for the advancement and diffusion of knowledge of the physics of fluids with special emphasis on the dynamical theories of the liquid, plastic and gaseous states of matter under all conditions of temperature and pressure.
Every year, the APS Division of Fluid Dynamics hosts a physical Gallery of Fluid Motion at its annual meeting—a room where stunning graphics and videos from computational or experimental studies showing flow phenomena are displayed. The most outstanding entries are selected by a panel of referees for artistic content and honored for their originality and ability to convey information. Past winners are published in the journal Physics of Fluids.
The Gallery of Fluid Motion at the 62nd APS Division of Fluid Dynamics Annual Meeting, held from November 22-24, 2009 at the Minneapolis Convention Center, highlighted a subset of submitted images and videos prior to the judging process.
2009 Image Gallery
Breakup of a Jet of Liquid in the Wind
Video by Sandeep Rana and Marcus Herrmann, Arizona State University
"We present a visualization of the primary atomization of a turbulent liquid jet injected into a turbulent gaseous cross-stream."
How the Sand Swimming Lizard Swims in Sand
Video by Ryan D. Maladen, Yang Ding, Adam Kamor and Daniel I. Goldman, Georgia Institute of Technology
"We use high-speed x-ray imaging to reveal how a small (~10cm) desert dwelling lizard, the sandfish (Scincus scincus), swims in a granular medium."
Moving Droplets with Light
Video by Han-Sheng Chuang, Aloke Kumar and Steven T. Wereley, Purdue University
"This fluid dynamics video showcases how optically induced electrowetting can be used to manipulate liquid droplets in open space."
Simulating a Jellyfish's Movement
Video by Johannes Tophøj Rasmussen, Francesca Storti, DTU; Jens Honore Walther, DTU and ETHZ; and, Diego Rosinelli and Petros Koumoutsakos, ETHZ
"We present simulations of the vortex dynamics associated with the self-propelled motion of jellyfish."
Merging Drops Jump on Hydrophobic Surface
Video by Jonathan Boreyko and Chuan-Hua Chen, Duke University
"When micrometric drops coalesce in-plane on a superhydrophobic surface, a surprising out-of-plane jumping motion was observed."
A Numerical Simulation of a Plunging Breaking Wave
Video by Paul Adams, Kevin George and Mike Stephens, ERDC DSRC; and, Douglas Dommermuth, Kyle A. Brucker and Thomas O'Shea, Science Applications International Corporation
"The video shows the results of a numerical simulation of a deep water plunging breaking wave."
Bouncing of a Droplet on Superhydrophobic Surface in AC Electrowetting
Video by Seung Jun Lee, Sanghyun Lee, and Kwan Hyoung Kang, POSTECH
"The controlled droplet jumping made by the resonant AC electrowetting shown in this movie could be a historical milestone in digital microfluidics ..."
Landing on the Moon: Cratering from a Jet
Video by Abe Clark, Bob Behringer, Duke University; and, John Brandenburg, ORBITEC
"This project characterizes crater formation in a granular material by a jet of gas impinging on a granular material, such as a retro-rocket landing on the moon."
Turbulent Flow Over a House in a Simulated Hurricane
Video by Zachary Taylor, Murray Morrison and Gregory Kopp, University of Western Ontario; and, Roi Gurka, Ben-Gurion University
"Every year hurricanes and other extreme wind storms cause billions of dollars in damage worldwide. A series of wind tunnel tests have been performed on a house in a simulated atmospheric boundary layer ..."
Saliva Filament
Video by Christian Wagner and Rainer Sattler, Saarland University; and Jens Eggers, University of Bristol
"The video shows the shadowgraph of a break-up of a capillary bridge of a droplet of saliva from a healthy donor."
Hovering Pyramid
Video by Bin Liu, Annie Weathers, Stephen Childress and Jun Zhang of New York University
"A free rigid object, here a hollow 'pyramid,' can hover quite stably against gravity in the oscillating airflow ..."
