DFD Virtual Press Room 2013
66th Annual Meeting of the APS DFD
November 24-26, 2013
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 66th 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.
Compound Droplets on a Fiber
Two compound droplets made of pure (in blue) and soapy (in red) water and silicon oil hanging on a horizontal fiber.
Bubbles in Complex Microgeometries
These micrographs display the flow deformation of air bubbles with highly viscous oils in microchannels having circular cavities.
Evolution of the flow structure produced by a shock wave accelerating a column of heavy gas.
Silicone oil trapped in a wedge is extracted by a surfactant solution that preferentially wets the confining walls.
Condensation of Droplets Inside Bubbles
When dry stagnant bubbles become saturated, small droplets begin to condense on the channel walls
3D Cylinder Wake
This plot is of 3D mean streamlines of the wake behind a cylinder immersed in a boundary layer measured by tomographic PIV.
Vortex Knots in Experiment
The creation and evolution of a trefoil vortex knot in water.
Galaxy in a Kitchen Sink
A spinning pentagonal hydraulic jump and logarithmic spiral waves downstream form when a jet of fluid hits a horizontal plate, as seen from below the plate.
Streamwise Vortices Generated by Rolling Up Shear Layers
Experimental flow visualization of a streamwise vortex generated by rolling up shear layers downstream of a swept, semi-span, backward facing step.
Charged Jumping Droplets
Long-exposure-time image of droplets merging and jumping on a superhydrophobic nanostructured tube. Droplets that leap off also repel each other due to their positive charge.
Merging Soap Films
Merging soap bubbles produce unexpectedly intricate structures.
Exploding Shocks and Bubbles
The images show the interaction between four laser induced shocks and bubbles in water. The shocks reflect at the bubbles as tensions nucleating a microscopic bubble cloud.
Sparkling fireworks scatter beautiful streaks of light with soothing sounds.
Hydrodynamic instabilities and art
When fluids of different density are poured on top of each other, they become unstable and mix in an interesting manner.
A Convention of UFOs
A thin film of Ionic Liquid is pulled up around droplets condensing on Ionic Liquid impregnated microtextured surface, giving them appearance of UFOs hovering on the surface.
