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 ...

An artistic pressions of a vortex-ring street analogue to the structure of magnetic field of a NDSTP, where the right- and left- handed vortex rings were highlighted by blue and red, respectively. The ...

Vortex rings, a mysterious and fascinating natural phenomenon, display breathtaking structures and behaviors in both air and electromagnetic waves. Imagine an air cannon that can shoot vortex rings, ...

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 ...

Helicopter safety researchers are to undertake formal analysis of the hazardous vortex ring phenomenon and the effectiveness of an alternative recovery and escape technique. The vortex ring state is ...

Some of the world’s most important discoveries – penicillin, vulcanized rubber and Velcro, to name a few – were made by accident. In fact, it’s been said that upward of half of all scientific ...
