The process of vortex ring generation and propagation has received substantial treatment in the literature. A common ring generation geometry consists of a piston moving through tube that exits into a ...
Vortex rings are toroidal structures of fluid characterised by closed-loop vorticity that provide a compelling example of coherent structures in fluid dynamics. Their dynamics involve complex ...
What do dolphins, humans and volcanoes have in common? They can all produce toroidal vortices of course! Surprised? Grab some food colour and a glass of water to find out how. 1. Fill a tall glass to ...
Turbulent ball: William Irvine, Takumi Matsuzawa and colleagues have used this apparatus to track turbulence with lasers and high-speed cameras. (Courtesy: Takumi Matsuzawa) Researchers in the US have ...
Some of the world’s most important discoveries – penicillin, vulcanized rubber and Velcro, to name a few – were made by accident. In fact, it’s been said that upward of half of all scientific ...
