While it’s moving quickly, the ring is very stable and retains its shape. 5. As it descends and slows down, the donut suddenly becomes unstable and breaks up - it's called a vortex breakdown.

Computer images of one of the vortex ring launcher prototypes LaRocco et al., Technologies 2024 Fighting fire usually involves water or foam, but they can be messy and environmentally destructive.

"A vortex ring is a donut-shaped vortex that is generated by an instantaneous ejection of fluid from a circular orifice," Fujio Akagi, the study's first author and an engineer at Fukuoka ...

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 becoming a ...
