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 ...

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 ...
