(Phys.org) —Physicists William Irvine and Dustin Kleckner of the University of Chicago, have for the first time, created a knotted vortex in a fluid. They describe how they printed 3D airfoils and ...

A nonlinear numerical model shows that internal and external flows can couple the first and second bending modes of a cantilever pipe, producing lock-in and post-flutter responses that remain periodic ...

Osaka Metropolitan University scientists investigated numerically the interaction between a quantized vortex and a normal fluid. Based on the experimental results, researchers decided the most ...

The 'air cannon,' a familiar toy for everyday play, is actually an excellent experimental device that allows us to witness ...

In this study, the non-linear dynamics of Taylor–Couette flow in a very small-aspect-ratio wide-gap annulus in a counter-rotating regime under the influence of radial through-flow are investigated by ...

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 ...

Containing a collection of some of the most striking photographs of fluid motions, this text also includes digitally generated visualizations from computational simulations of flow phenomena, and ...

Watching LEGO minifigures spin around in a fluid vortex, itself created with motorized LEGO, is a surprisingly hypnotic experience. The list of things people can do with LEGO is literally endless.

Local regulatory frameworks increasingly require factory facilities to undergo rigorous energy efficiency audits. Operating teams must now track thermal energy, steam consumption, and fuel gas usage ...
