Gallery of Fluid Motion
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. The outstanding entries, selected by a panel of referees for artistic content, originality and ability to convey information, will be honored during the meeting, placed on display at the Annual APS Meeting in March of 2012, and will appear in the annual Gallery of Fluid Motion article in the September 2012 issue of the American Institute of Physics' journal, Physics of Fluids. Past winners are published in the journal Physics of Fluids.
Physics of Fluids
In conjunction with the 64th APS Division of Fluid Dynamics Annual Meeting, held from November 20-22, 2011, in Baltimore, Maryland, a subset of these images and videos are available for viewing prior to the judging process.

Direct Numerical Simulation of Stratified Turbulence
Density fluctuations in a turbulent liquid are imaged using direct numerical simulation, showing the competition between two turbulence-controlling forces: shear and stratification.
Nematode C. elegans Swimming in a Drop
A top-down view of a nematode swimming within an aqueous drop shows the worm sticking to the drop edge.
Bouncing in Puddles
A ball is seen in sequential images as it rebounds from bouncing in a puddle of water.
Trapping of a Red Blood Cell Inside a Fluid Filament
A thin filament forms during the breakup of a fluid drop, trapping a red blood cell.
The Poppy: An Imploding Circular Water Wave
A circular, converging water wave, resembling the shape of a remembrance poppy, was created by rapidly retracting a gate that separated a region of high water level from a region of low water level.
Harnessing Sloshing as a Passive Dampener
Water is shown sloshing in a hollow, transparent sphere.
Revealing Hummingbirds’ Tongue Tricks
This snapshot, taken with a high-speed camera, shows the tongue tip of a hummingbird drinking nectar out of a “transparent flower.”
Instabilities and Flow Structures in a Rotating Channel
A snapshot from a numerical experiment of turbulent flow between two parallel plates rotating spanwise shows strong turbulence (hairpin-like structures with one or two legs) near the lower wall and little turbulence but large, rolling waves (dark blue) near the upper wall.
Visualization of Streamlines with Halos
This image is an illustration of interacting streamlines.
Bubble Entrainment by a Plunging Jet
A plunging water jet creates deformed bubbles that are forced beneath the surface by the high-speed fluid.
Dancing in the Pipe
Cross-section snapshots of a curved pipe flow show a pair of vortices as they shift position over time, appearing to ‘dance’ in the turbulent flow conditions.
Structure of Line Plumes in Convection across a Membrane
A top-down view of line plumes forming on a horizontal membrane separating brine above water.
