"This process acts in tenths of a second, so the ring is emitted impulsively into the air domain. Due to its own momentum, thermal buoyancy and to the inertia of the rotating fluid, the vortex ...

"We found a more efficient way of solving [a] problem." Researchers stunned after discovering breakthrough firefighting tool delivers unexpected results: 'We were blown away' first appeared on The ...

The process of vortex ring generation and propagation has received substantial treatment in the literature. A common ring generation geometry consists of a piston moving through tube that exits into a ...

The central part of the disc thus formed soon disappears, and consequently a ring form results. This is a very slowly whirling vortex ring. As it proceeds, the radius of the ring is augmented ...

The polar vortex is an area of low pressure and cold air circulating around the poles in the stratosphere — a layer in the atmosphere hovering between 7.5 and 31 miles (12 and 50 kilometers ...

The Vortex of Putrescence is a Sorcery introduced in Elden Ring: Shadow of the Erdtree. Sorcery used by the Putrescent Knight. Launches a whirl of putrescent jets that bathe the surroundings of ...

Last autumn, AccuWeather highlighted the transition from winter to spring as the period when the polar vortex could pay a visit to the U.S. With plenty of cold air in place, the colder pattern ...
