Newswise: Gallery of Fluid Motion: Capturing Liquids and Gases in Action

Gallery of Fluid Motion: Capturing Liquids and Gases in Action

American Physical Society's Division of Fluid Dynamics

Tears stream down your face. A beer flows down the side of a pint glass. Fluid mechanics is central to understanding the world around us. The beauty of fluid motion was on display last week in Seattle, where more than 3,000 scientists gathered for the 72nd Annual Meeting of the American Physical Society’s Division of Fluid Dynamics. Created in 1987, the Gallery of Fluid Motion (GFM) is the premier visual record of contemporary fluid mechanics.

Fire Ants’ Raft Building Skills React as Fluid Forces Change

American Physical Society's Division of Fluid Dynamics

Fire ants build living rafts to survive floods and rainy seasons. Georgia Tech scientists are studying if a fire ant colony’s ability to respond to changes in their environment during a flood is an instinctual behavior and how fluid forces make them respond.

Chemical Herders Could Impact Oil Spill Cleanup

American Physical Society's Division of Fluid Dynamics

Oil spills in the ocean can cause devastation to wildlife, so effective cleanup is a top priority. Research shows the effects of chemical herders, which are agents that may be used to concentrate oil spills, on wave breaking.

Harvesting Fog Can Provide Fresh Water in Desert Regions

American Physical Society's Division of Fluid Dynamics

Fog harvesting is a potential practical source of fresh water in foggy coastal deserts, and current solutions rely on meter scale nets/meshes. The mesh geometry, however, presents a physiologically inappropriate shape for millimeter scale bulk bodies, like insects.

Fossils Reveal Swimming Patterns of Long Extinct Cephalopod

American Physical Society's Division of Fluid Dynamics

Computational fluid dynamics can be used to study how extinct animals used to swim. Scientists studied 65 million-year-old cephalopod fossils to gain deeper understanding of modern-day cephalopod ecosystems.

Low Frequency Sound May Predict Tornado Formation

American Physical Society's Division of Fluid Dynamics

How can you tell when a storm is going to produce a tornado even before the twister forms? Research from Oklahoma State University and University of Nebraska-Lincoln indicates prior to tornado formation, storms emit low-frequency sounds.

Reports of Jupiter’s Great Red Spot Demise Greatly Exaggerated

American Physical Society's Division of Fluid Dynamics

The shrinking of the clouds of the Great Red Spot on Jupiter has been well documented with photographic evidence from the last decade. However, researchers said there is no evidence the vortex itself has changed in size or intensity.

Fluid Dynamics Taught Through Dance

American Physical Society's Division of Fluid Dynamics

A collaboration at University of Michigan is taking a unique approach to fluid mechanics by teaching it through dance, creating Kármán Vortex Street, a dance improvisation guided by physics properties.

Not All Changeups Are Created Equal; Seam Shifted Wake Baffles Hitters

American Physical Society's Division of Fluid Dynamics

While changing the rotation rate/axis of a thrown baseball has long been a weapon in a pitcher’s arsenal, some pitchers manipulate the baseball’s wake to create unexpected movement from a familiar delivery of his changeup.

Heating Techniques Could Improve Treatment of Macular Degeneration

American Physical Society's Division of Fluid Dynamics

Age-related macular degeneration is the primary cause of central vision loss and results in the center of the visual field being blurred or fully blacked out. Though treatable, some methods can be ineffective or cause unwanted side effects. Jinglin Huang, a graduate student in medical engineering at Caltech, suggests inefficient fluid mixing of the injected medicine and the gel within the eye may be to blame.
