Vortices contain substantial energy in the circular motion of the fluid. In an ideal fluid this energy can never be dissipated and the vortex would persist forever. However, real fluids exhibit viscosity and this dissipates energy very slowly from the core of the vortex. It is only through dissipation of a vortex due to viscosity that a vortex ...
Vortex is the proper term for a whirlpool that has a downdraft. [citation needed] In narrow ocean straits with fast flowing water, whirlpools are often caused by tides. Many stories tell of ships being sucked into a maelstrom, although only smaller craft are actually in danger. [2]
A Laguerre-Gaussian beam is an optical vortex with a line singularity along the beam axis. An optical singularity is a zero of an optical field. The phase in the field circulates around these points of zero intensity (giving rise to the name vortex). Vortices are points in 2D fields and lines in 3D fields (as they have codimension two).
The Oregon Vortex is a roadside attraction that opened to tourists in 1930, [1] located on Sardine Creek [2] in Gold Hill, Oregon, in the United States. It consists of a number of interesting effects, which are gravity hill optical illusions , but which the attraction's proprietors propose are the result of paranormal properties of the area.
A circumpolar vortex, or simply polar vortex, is a large region of cold, rotating air; polar vortices encircle both of Earth's polar regions. Polar vortices also exist on other rotating, low- obliquity planetary bodies . [ 1 ]
