Step inside the strange world of a superfluid, a liquid that can flow endlessly without friction, defying the common-sense ...

Knots are not just for shoelaces and sailing lines. In the last decade, physicists have shown that swirling liquids can ...

The study of vortex dynamics in fluid mechanics is critical for both advancing aeronautical design and minimising flow-induced hazards. At its core, vortex dynamics examines the formation, evolution, ...

Vortex tubes are a key ingredient of turbulence, which is widely studied in classical physics. The motion of vortex tubes is relevant in a wide range of scenarios, such as the formation of hurricanes, ...

An Australian-led study has provided new insight into the behaviour of rotating superfluids. A defining feature of superfluids is that they exhibit quantised vortices – they can only rotate with one, ...

Vortex dynamics simulations reveal reconnection, an important property linked with creation of turbulence cascade, fluid mixing, and aerodynamic noise generation. Turbulent pipe flow simulated at high ...

Fluid flow across a flexible or elastically mounted structure causes vibrations due to vortex shedding and other similar instabilities, like galloping. The flow-induced vibrations (FIV) are ...

There was once a saying from the renowned American physicist Richard Feynman about turbulence. He said that it remains to be the most important "unsolved" problem in classical physics. The challenge ...

The knots in your shoelaces are familiar, but can you imagine knots made from light, water, or from the structured fluids ...

A century-old physics question had scientists and mathematicians in knots, until two researchers at the University of Chicago annihilated them. Dustin Kleckner, a postdoctoral scientist, and William ...
