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 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.
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.
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.
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.
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.
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.
Inspired by their use in mechanical systems, Massachusetts Institute of Technology researchers are testing a magnetically-actuated fluidic valve to use in trauma patients suffering from hemorrhage.
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.
When it comes to archery, choosing the right feathers for an arrow is the key to winning. This necessity for precision makes it crucial to understand how environment and design effect arrows in flight.
Trapped water in the ear canal can cause infection and even damage, but it turns out that one of the most common methods people use to get rid of water in their ears can also cause complications. Researchers show shaking the head to free trapped water can cause brain damage in small children.
