Jet (fluid)


Jet (fluid)

A jet is a coherent stream of fluid that is projected into a surrounding medium, usually from some kind of a nozzle or aperture. Jets can travel long distances with dissipating. In the Earths atmosphere there exist jet streams that travel thousands of miles.

Some animals, notably cephalopods use a jet to propel themselves in water. Similarly, a jet engine as it name suggests, emits a jet used to propel rockets, aircraft, Jetboats, and submarines.

*jet engine - any machine propelled by a jet
*nozzle - how a jet is formed
*jet damping - a jet carries away angular momentum from a device emitting it
