Physics of Fluids is a peer-reviewed monthly scientific journal on fluid dynamics, published by the American Institute of Physics with cooperation by the American Physical Society's Division of Fluid Dynamics, since 1958. The focus of the journal is on the dynamics of fluids—gases, liquids and multiphase flows—and the journal contains original research resulting from theoretical, computational and experimental studies. Until 1988, the journal covered both fluid and plasma physics. From 1989 until 1993, the journal was split into two separate ones: Physics of Fluids A covered fluid dynamics, while Physics of Fluids B was on plasma physics. In 1994, Physics of Plasmas was split off and the fluid dynamics journal continued under its original name, Physics of Fluids. Since 1985 Physics of Fluids presents the Gallery of Fluid Motion, containing award-winning photographs, images and visual streaming media of fluid flow, as resulting from experiments and computations. The annual "François Naftali Frenkiel Award" was established by the American Physical Society in 1984 and rewards a young scientist who has published a paper—containing significant contributions to fluid dynamics—in this
How the kettle got its whistle
(Phys.org) —Researchers have finally worked out where the noise that makes kettles whistle actually comes from – a problem which has puzzled scientists for more than 100 years.
The physics of ocean undertow: Small forces make a big difference in beach erosion
People standing on a beach often feel the water tugging the sand away from under their feet. This is the undertow, the current that pulls water back into the ocean after a wave breaks on the beach.
What makes flying snakes such gifted gliders?
Animal flight behavior is an exciting frontier for engineers to both apply knowledge of aerodynamics and to learn from nature's solutions to operating in the air. Flying snakes are particularly intriguing to researchers because ...
Bats inspire 'micro air vehicle' designs
By exploring how creatures in nature are able to fly by flapping their wings, Virginia Tech researchers hope to apply that knowledge toward designing small flying vehicles known as "micro air vehicles" with flapping wings.
Smooth sailing: Rough surfaces that can reduce drag
From the sleek hulls of racing yachts to Michael Phelps' shaved legs, most objects that move through the water quickly are also smooth. But researchers from UCLA have found that bumpiness can sometimes be better.
Strange behavior of bouncing drops demonstrates pilot-wave dynamics in action (w/ Video)
A research team led by Yves Couder at the Université Paris Diderot recently discovered that it's possible to make a tiny fluid droplet levitate on the surface of a vibrating bath, walking or bouncing across, propelled by ...
New experiments offer insight into how insects fly and how to design tiny flying robots
Researchers have identified some of the underlying physics that may explain how insects can so quickly recover from a stall in midflight—unlike conventional fixed wing aircraft, where a stalled state often leads to a crash ...
Whither the teakettle whistle: Breakthrough in breakfast musings
Despite decades of brewing tea in a whistling kettle, the source and mechanism of this siren sound of comfort has never been fully described scientifically. Acknowledging the vibrations made by the build-up of steam escaping ...
How Earth's rotation affects vortices in nature
What do smoke rings, tornadoes and the Great Red Spot of Jupiter have in common? They are all examples of vortices, regions within a fluid (liquid, gas or plasma) where the flow spins around an imaginary straight or curved ...
Simulations helps scientists understand and control turbulence in humans and machines
Aerospace engineers from the University of Illinois, Urbana-Champaign are using the National Science Foundation-supported Stampede supercomputer to explore how jets in general, like those on modern aircraft and inside the ...
