I mentioned last week that fans of fluid dynamics were in for a real treat with The American Physical Society's (APS) Division of Fluid Dynamics (DFD) meeting held in San Diego, November 19-20, 2012, and it did not disappoint. For more APS DFD stories ranging from shockwaves to the structure of an owl's wing, read on.

Mach 3 Bubble Shockwaves

What happens when a Mach 3 shockwave slams into a helium bubble? Researchers needed a supercomputer cluster to simulate the phenomenon, revealing how density and vorticity evolve during the process. Read more >>

Sound Bullets in Water

Researchers at Caltech have developed a nonlinear acoustic lens that can focus high-amplitude pressure pulses into compact "sound bullets" in water. Read more >>

Dreamy Images Reveal the Beauty of Physics in Motion

The images, part of the American Physical Society's Division of Fluid Dynamics Gallery of Fluid Motion, are drawn from the most artistic and evocative research presented at the Fluid Dynamics annual meeting. Read more >>

Owls May Have Solution to Conventional Aircraft Noise

Researchers from the University of Cambridge, England, are studying the owl's wing structure to better understand how it mitigates noise so they can apply that information to the design of conventional aircraft. Read more >>
