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 61st APS Division of Fluid Dynamics Annual Meeting, held from November 23-25, 2008 at the Henry B. Gonzalez Convention Center in San Antonio, highlighted a subset of submitted images and videos prior to the judging process.
2008 Image Gallery
Video by James C. Bird and Howard A. Stone, Harvard University.
"We experiment with injecting a continuous stream of gas into a shallow liquid, similar to how one might blow into a straw placed at the bottom of a near-empty drink..."
Video by Jeremy O. Marston, Institute of Chemical and Engineering Sciences; Sigurdur T. Thoroddsen, National University of Singapore, Singapore.
"When a viscous drop impacts onto a pool of lower viscosity liquid, a new jetting phenomenon is observed; an Apex Jet."
Video by: Anup A. Shirgaonkar, Oscar M. Curet, Neelesh A. Patankar and Malcolm A. MacIver, Northwestern University.
"The gymnotiform mode of aquatic locomotion is characterized by the use of an elongated anal fin, generically referred to as a ribbon fin. The extraordinarily maneuverable weakly electric black ghost knifefish (Apteronotus albifrons) uses this mode of locomotion."
Video by William H. Cabot, Andrew W. Cook, Kyle J. Caspersen, James N. Glosli, Liam D. Krauss, Paul L. Miller, David F. Richards, Robert E. Rudd and Frederick H. Streitz, Lawrence Livermore National Lab.
"We present a fluid dynamics video showing the results of a 9-billion atom molecular dynamics simulation of complex fluid flow in molten copper and aluminum."
Video by: Tadd T. Truscott, Jeffrey M. Aristoff and Alexandra H. Techet, Massachusetts Institute of Technology.
"The hydrodynamics associated with water-entry of spheres can be highly variable with respect to the material and kinematic properties of the sphere. This series of five fluid dynamics videos illustrates several subtle but interesting variations."
Video by: Enrique Soto Castruita and Andrew Belmonte, Pennsylvania State University.
"We study the instabilities occurring during the burst of an air balloon in a liquid."
Video by: Minhee Lee and Ho-Young Kim, Seoul National University, Korea.
"This fluid dynamics video illustrates the method to micropattern a liquid on a solid surface with drop impact."
Video by: Bob Blackstock, Laminar Sciences Corp., Agoura Hills, CA.
"Flow visualization via streaming birefringence. Bursts of jets as well as stable free jets flowing into quiescent chambers."
Video by Carlos L. Perez and Jonathan D. Posner, Mechanical and Aerospace Engineering, Arizona State University.
"Under the application of an external electric field, particles in non-dilute colloidal suspensions can chain and result in unsteady fluid motion, under some conditions."
