In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime. [2] The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object.
A whirlpool is a body of rotating water produced by opposing currents or a current running into an obstacle. [1] [clarification needed] Small whirlpools form when a bath or a sink is draining. More powerful ones formed in seas or oceans may be called maelstroms (/ ˈ m eɪ l s t r ɒ m,-r ə m / MAYL-strom, -strəm).
Located between the eddy and the main current, the eddy line is a swirling seam of green and sometimes white water. Eddy lines vary in size based on the size of the water column, the gradient of the section, and the obstacle creating the eddy.
Plunge pools are often very deep, generally related to the height of the fall, the volume of water, the resistance of the rock below the pool and other factors. [4] The impacting and swirling water, sometimes carrying rocks within it, abrades the riverbed into a basin, which often features rough and irregular sides. Plunge pools can remain long ...
The swirling motion of a fluid and the reverse current created when the flow regime experiences turbulence, such as when an obstacle blocks part of the path of flow. Ekman layer The layer in a fluid in which there is a force balance between the pressure-gradient force, the Coriolis force, and turbulent drag.
Astronomers used the Hubble Space Telescope to make a landmark discovery of water vapor in the atmosphere of a planet just twice Earth’s diameter in size.
Earlier this month, Columbus Utilities in Columbus, a small city northeast of Madison, won the gold medal at the National Rural Water Association's 25th Annual Great American Water Taste Test.
An intuitive description of this mechanism is what is defined as eddy-centric-analysis based on sea-surface level. [3] In the Northern hemisphere, anticlockwise rotation in cyclonic eddies creates a divergence of horizontal surface currents due to the Coriolis effect, leading to a dampened water surface. To compensate the inhomogeneity of ...
