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 ...

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 ...

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 ...

"The main interest is to try to predict the consequences of surgery and maybe plan the operation to minimize the effects on voice," says Luc Mongeau, an associate professor of mechanical engineering ...

A complex maze of lasers, lenses and mirrors has been used to twist light into a vortex shaped like a doughnut. Vortex rings are common in fluids – think of smoke rings floating in air or underwater ...

Filou had to decide which of the vortex rings was larger based only on the feeling as the water swirled across his whiskers, tapping one of two green balls on either side of his head to let the ...

Dozens of circular loops made from smoke and volcanic gas are rising from a peculiar vent on Mount Etna every day. When you purchase through links on our site, we may earn an affiliate commission.
