A DROP of liquid heavier than water, for example blue or red ink, submerged quietly into still water, encounters the resistance of the medium and becomes flatter in its form in the course of its ...

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 ...

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 ...

STORY: Volcanic vortex rings are natural, near-perfect circles of gas emitted from a volcano under specific conditions and scientists say Mount Etna emits more than any other volcano on earth. It is a ...

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 ...
