Eddy Guide, Meaning , Facts, Information and Description
In fluid dynamics, an eddy is the swirling of water and the reverse current created when water flows past an obstacle. The moving water creates a space devoid of downstream-flowing water on the downstream side of the object. Water behind the obstacle flows into the void creating a swirl of water on each edge of the obstacle, followed by a short reverse flow of water behind the obstacle flowing upstream, toward the back of the obstacle. This phenomenon is most visible behind large emergent rocks in swift-flowing rivers.Another possible turbulence is the vortex. This notion is rather aplied to gases than to fluids. Here, no void is created, but only an area of lower pressure, but again, a backflow causes the gas to rotate.
Eddy is also a name, usually an abbreviation of Edward.
