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 ...

Intrigued by a grainy video from 1992, [Destin] from Smarter Every Day decided to jump in and fund his own research into the strange phenomenon of vortex ring collisions. This hack started with a ...

Helicopter safety researchers are to undertake formal analysis of the hazardous vortex ring phenomenon and the effectiveness of an alternative recovery and escape technique. The vortex ring state is ...

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 ...

Smoke rings are being seen in a new light. Doughnut-shaped structures called vortex rings are sometimes seen swirling through fluids. Smokers can form them with their mouths, volcanoes can spit them ...

The study of vortex ring dynamics centres on understanding the formation, evolution and decay of toroidal vortices generated by pulsed fluid jets. These phenomena are crucial in a wide range of ...

Air rings blown by dolphins swimming underwater and rings of smoke emitted by jet engines are just two examples of vortex rings. These doughnut-shaped structures and their mesmerizing movement have ...

Better understanding the formation of swirling, ring-shaped disturbances -- known as vortex rings -- could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to ...
