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 ...
A group of hikers look at one of the smoke rings Europe's most active volcano, Mount Etna, is blowing scores of ethereal "vortex rings" every day from a single vent located in one of its most active ...
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 ...
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 ...

What it means when a polar vortex 'breaks'
The term "polar vortex" gained notoriety back in 2014 due to extreme winter weather, but there's more to this phenomenon than ...
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 ...
