2014 Image Gallery
DFD Virtual Press Room 2014
67th Annual Meeting of the APS DFD
San Francisco, California
November 23-25, 2014
Gallery of Fluid Motion
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.
A panel of referees selects the most outstanding entries based on artistic content, originality, and their ability to convey information. The 67th Annual Meeting Image Gallery archives a subset of these images and videos on the APS DFD website. Outstanding entries are honored during the Meeting, placed on display at the Annual APS March Meeting, and published in the annual "Gallery of Fluid Motion" in the September issue of the American Institute of Physics' journal, Physics of Fluids. Past winners are also published in the Physics of Fluids.
Hydrodynamic Quantum Analogs

Spray Formation of a Gel Using Impinging Jets
Impinging jet spray formation of a 1.0 wt.-% kappa carrageenan gel at two different atomization regimes depending on the jet Herschel-Bulkley Extended (HBE) generalized Reynolds number.
Unexpected Trapping of Particles 2
Once a particle migrates into the vortex tube, it follows a heart-shaped helical orbit.

Prepare honey and steel beads.
Dancing beads, which try to oscillate periodically while falling in a viscous fluid
Subsequent configurations of beads settling in honey (top), in silicon oil (middle) and in a viscous fluid, which moves according to the Stokes equations (bottom). Gravity points down.
The Lions of the Piazza del Popolo
The turbulent water sheet expectorated by the lions of the Piazza del Popolo in Rome is a caricatural example of random fluctuations mediating liquid fragmentation by hole nucleation, growth and ligament breakup.
Cavitation bubbles and Tethered Particles
A cavitated bubble in water interacts with a tethered particle.
