This phenomenon is naturally observed behind large emergent rocks in swift-flowing rivers. An eddy is a movement of fluid that deviates from the general flow of the fluid. An example for an eddy is a vortex which produces such deviation. However, there are other types of eddies that are not simple vortices.
The large eddies are unstable and eventually break up originating smaller eddies, and the kinetic energy of the initial large eddy is divided into the smaller eddies that stemmed from it. These smaller eddies undergo the same process, giving rise to even smaller eddies which inherit the energy of their predecessor eddy, and so on.
In fluid dynamics, eddy diffusion, eddy dispersion, or turbulent diffusion is a process by which fluid substances mix together due to eddy motion. These eddies can vary widely in size, from subtropical ocean gyres down to the small Kolmogorov microscales , and occur as a result of turbulence (or turbulent flow).
This phenomenon is known as eddy saturation. (a) Time series of the ACC (blue) and EKE (red) in an eddy saturated quasigeostrophic coupled ocean-atmosphere model with an applied with stress, which is increased with a step function by 50% (black).
Eddy pumping is a component of mesoscale eddy-induced vertical motion. Such vertical motion is caused by the deformation of the pycnocline. It can be conceptualised by assuming that ocean water has a density surface with mean depth averaged over time and space.
Eddy currents in conductors of non-zero resistivity generate heat as well as electromagnetic forces. The heat can be used for induction heating. The electromagnetic forces can be used for levitation, creating movement, or to give a strong braking effect. Eddy currents can also have undesirable effects, for instance power loss in transformers.
Eddy current array (ECA) and conventional ECT share the same basic working principles. ECA technology provides the ability to electronically drive an array of coils ( multiple coils) arranged in specific pattern called a topology that generates a sensitivity profile suited to the target defects.
Brudziński's sign or a Brudziński sign is any of three medical signs, all of which may occur in meningitis or meningism.All three are named after Józef Brudziński. [1] In English, the name is often written without the diacritic (like many borrowed words) (Brudzinski) and is pronounced / b r uː ˈ dʒ ɪ n s k i /.
