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 ...

A team of researchers discovered an extraordinary property of vortex rings—how dolphins propel themselves underwater—that science had overlooked for a century. Scientists from New York University and ...

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 ...

Air cannons produce visible vortex rings by generating rotating air pressure differences, while electromagnetic cannons emit electromagnetic vortex pulses using coaxial horn antennas. The ...

The volcano, one of Europe’s most active, has been spewing volcanic vortex rings at a rapid pace. But that doesn’t mean a big explosion is on the way, one expert says. By Elisabetta Povoledo Reported ...
