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

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 ...

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, ...

A team of researchers affiliated with UNIST has made a significant breakthrough by mathematically proving that a special type of vortex pair, called the Sadovskii vortex patch, can exist within ideal ...

Liquid helium-4, which is in a superfluid state at cryogenic temperatures close to absolute zero (-273°C), has a special vortex called a quantized vortex that originates from quantum mechanical ...

Researchers have created a model that describes the spread and speed of tornado-like vortex tubes in superfluids. This work expands on a previous study that reported experimental results obtained in ...

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 ...

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 ...

AbstractThe Sadovskii vortex patch is a traveling wave for the two-dimensional incompressible Euler equations consisting of an odd symmetric pair of ...

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 ...

In a new Nature Physics study, researchers created particle-like so-called “vortex knots” inside chiral nematic liquid ...
