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 ...

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 ...

Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar ...
