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
Why a latte is less likely to spill than a coffee
Carrying a full cup of coffee from the kitchen to the dining room can be precarious for a sleepy-eyed caffeine addict who might accidentally send a wave of java sloshing over the rim. But add a bit of foam ...
Laser-guided sea monkeys show how zooplankton migrations may affect global ocean currents
Sea monkeys have captured the popular attention of both children and aquarium hobbyists because of their easily observable life cycle—sold as dehydrated eggs, these tiny brine shrimp readily hatch, develop ...
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 ...
Dynamics of tears: A cure for dry eye could be a blink away
A treatment for dry eye—a burning, gritty condition that can impair vision and damage the cornea—could some day result from computer simulations that map the way tears move across the surface of the eye.
New super waterproof surfaces cause water to bounce like a ball
(Phys.org) —In a basement lab on BYU's campus, mechanical engineering professor Julie Crockett analyzes water as it bounces like a ball and rolls down a ramp.
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.
Physicists working to cure 'dry eye' disease
The eye is an exquisitely sensitive system with many aspects that remain somewhat of a mystery—both in the laboratory and in the clinic. A U.S.-based team of mathematicians and optometrists is working to change this by ...
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 ...
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 ...
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.
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 ...
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 ...
Cat's eyes: Designing the perfect mixer
As any amateur baker knows, proper mixing is crucial to a perfect pastry. Mix too little and ingredients will not be evenly distributed; beat instead of fold, and a soufflé will fall flat. Mixing strategies ...
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.
Shifting winds in turbine arrays
Researchers modeling how changes in air flow patterns affect wind turbines' output power have found that the wind can supply energy from an unexpected direction: below.
