But the biggest vortex rings on Earth are not made by dolphins or humans. Volcanoes sometimes emit huge ring shaped clouds of steam and gas up to 200 metres in diameter.

Vortex rings are pretty cool, and electromagnetism even cooler. Now, a team of physicists have found a way to combine the two phenomena, creating the electromagnetic vortex cannon. In fluids ...

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 ...

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 ...

Engineers at Ohio State University have now developed handheld tools that cleanly extinguish fires with 'ionic wind’ and vortex rings. Fighting fire usually involves water or foam, but they can ...

Vortex rings reach the top and bottom edges of the shield and form a high-velocity entrainment flow. It is suggested that vortex rings capture small-sized particles, i.e., ...

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 ...

As the eight vortex rings collided, they created a roughly spherical ball of turbulence at the centre of the tank. Not only was the ball completely isolated from the tank’s walls; it could be ...

The “volcanic vortex rings” come from a combination of rapid gas release and the vent shape of the new crater. SWNS “Even if a volcano has the capability to create smoke rings, strong winds ...
