Furthermore, the way a flamingo jerks its head straight upward from the water creates a vortex along the vertical axis. Its beak chattering, in which it opens and shuts its lower beak at a rate of ...

Vortex Ring: A toroidal region of rotating fluid characterised by a closed-loop configuration of vorticity. Reynolds Number: A dimensionless parameter that quantifies the ratio of inertial to ...

The study, which was published in the Proceedings of the National Academy of Sciences, revealed new insights into vortex dynamics within superfluid helium, a remarkable liquid that exhibits zero ...

A non-uniform vortex fluid expands to form a Rankine vortex. (Darker colours represent high ... “Our study overcomes this challenge by providing an exact solution to the vortex dynamics. ...

In fluid dynamics, a vortex is created when liquid revolves around a central axis. These are often seen in whirlpools, in the wake of boats, or in the bottom of the bath when you pull out the plug.

A vortex is a rotating region of fluid, such as air or water, characterized by intense rotation. Common examples include typhoons and tornadoes frequently observed in news reports.

The researchers observed how tiny waves in the fluid interacted with the vortex, a process that mimics the way that cosmic fields in space interact with rotating black holes.

Breakthrough discovery in vortex dynamics. ... Their findings establish a universal physical law governing vortex interactions across multiple fluid types and temperature ranges.

The study’s authors write that understanding how flamingos use fluid dynamics to improve collection of sediments and prey could help design systems to better capture other tiny particles, like ...
