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 ...

Quantized Vortex Rings in Superfluid Helium Vortex rings analogous to smoke rings in air can be produced in liquid helium. They move in strange ways and exhibit discrete quantum effects on a large ...

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.

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 ...
