Definition of vortex in English:

vortex

nounPlural vortices, Plural vortexes ˈvɔːtɛksˈvɔrˌtɛks
  • A whirling mass of fluid or air, especially a whirlpool or whirlwind.

    旋涡;旋风

    we were caught in a vortex of water
    figurative a swirling vortex of emotions

    情感的旋涡。

    Example sentencesExamples
    • They save energy by slaloming back and forth between the vortices, or whirlpools.
    • He studied the dynamics of viscous fluids and the theory of vortices with applications to aeronautics in mind.
    • Currents passing around the tops of seamounts also create eddies and other vortices that can catch, hold and concentrate small plants and animals-phytoplankton and zooplankton-in suspension near summits.
    • The denser sand on top sinks while light sand on the bottom rises, creating swirling vortices akin to the convection rolls that are common in gases heated from below.
    • The five to 12 separate finlets behind the anal and second dorsal fins may allow the tail to push against less turbulence by preventing vortices from forming in water flowing toward the tail.
    • As this material approaches the black hole, it swirls in a vortex, like water swirling down a drain.
    • Inside clouds tiny vortices created by the wind spin water-sodden dust particles into clusters, where they meld to form raindrops, say the authors.
    • The counterclockwise winds around the vortex often push Arctic air south over the USA.
    • The magnetic fields of these vortices cause them to repel one another just as like-oriented magnets do.
    • These vortices however, are unstable masses of air that can cause lots of problems to fly in.
    • These grooves create microscopic vortices in the water next to the swimmer, thereby disturbing the flow of water along the body and reducing the surface friction drag.
    • Even though the flow of vortices is almost transparent, it should be possible in time, to measure the flow power, the direction and plane that they take as they spin and propel away from the swimmer's body.
    • A descent through your rotor wash creates swirling vortices that spoil lift, so the more power you add, the worse it gets, and the faster you fall.
    • The pressure of the water in these swirling vortices is lower than it is in the undisturbed fluid around the fish.
    • Dust devils are swirling vortexes that can tower several miles high and a quarter-mile (about a half a kilometer) wide at the base.
    • Unlike wind tunnel test for airliners, there is no way to confirm exactly if or how vortices and shock waves form off of wing tips or other geometries.
    • The resulting vector flow fields allow for the study of the distribution of velocity, vorticity and vortices.
    Synonyms
    whirlwind, whirlpool, gyre, maelstrom, eddy, swirl, swirling, countercurrent, counterflow
    literary Charybdis

Derivatives

  • vortical

  • adjective ˈvɔːtɪk(ə)lˈvɔrdək(ə)l
    • (of motion) like that of a vortex; whirling.

      the particles descend with vortical motion
      Example sentencesExamples
      • the vortical flow inside the left ventricle
      • Detailed flow visualization in flapping foils provides a more complex picture: The vortical patterns close partially on themselves to form apparent ring loops, but the vorticity of each loop connects all the way back to the foil.
      • Predictions of the effects of both observed vortical flow patterns and pressure distributions on the carapace were consistent with actual forces and moments measured using the force balance.
      • This concept is not so simple to apply, because the average flow is affected by the unsteady vortical patterns through the Reynolds stresses.
  • vortically

  • adverb
    • As soon as pitting has started and significant current flows, the electrolyte starts to flow vortically according to the magnetohydrodynamic effect.
      A discussion of a methodology for the study of heat transfer in the vortically enhanced mixing of heating and vaporizing sprays is provided.
  • vorticity

  • noun vɔːˈtɪsɪtivɔrˈtɪsədi
    mass noun
    • A whirling motion of fluid or air.

      tornado vorticity
      Example sentencesExamples
      • a weakening in the vorticity of the Gulf Stream
      • Because of the nature of inviscid flow, these techniques are often called vortex methods because point vorticity can be used to satisfy a required non-penetrating boundary condition at the fish surface.
      • It is shown that the internal wave field modulated the vorticity field so as to satisfy conservation of potential vorticity.
      • We assumed the vortex rings to be circular and to contain all vorticity.
  • vorticose

  • adjective vɔːtɪˈkəʊs
    • Additionally, it should be noted that the vorticose air motions produced by the moving parts of the machine circulate dust which is deposited on the yarns and makes them undesirably dirty.
      Example sentencesExamples
      • This vorticose motion of the wind is called a cyclone.
  • vorticular

  • adjective vɔːˈtɪkjʊlə
    • An additional stabilizing feature within our Plasma unit is the recirculation of heated mass, in a vorticular fashion within the Plasma flow.
      Example sentencesExamples
      • Sometimes, tornadoes in our area are referred to by euphemisms like ‘intense vorticular clouds’, ‘freak wind storms’, and so forth.
      • The structured water is then locked into place through physical forces of vorticular motion and magnetic moments so the water clusters stabilize.
      • That's where the air is entering the combustion chamber in a vorticular pattern.

Origin

Mid 17th century: from Latin vortex, vortic-, literally 'eddy', variant of vertex.

  • verse from Old English:

    In his poem ‘Digging’ (1966), Seamus Heaney resolves to carry on the family tradition of digging the soil by ‘digging’ himself, not with a spade like his father and grandfather, but with a pen. The link between agriculture and writing poetry goes all the way back to the origin of the word verse, as Latin versus meant both ‘a turn of the plough, furrow’ and ‘a line of writing’. The idea here is that of a plough turning and marking another straight line or furrow. Versus is also the source of versatile (early 17th century) and version (Late Middle English), and it is based on Latin vertere ‘to turn’, from which vertebra (early 17th century), vertical (mid 16th century), vertigo (Late Middle English), and many other words such as adverse (Late Middle English), convert (Late Middle English), and pervert (Late Middle English) ‘turn bad’. Vortex (mid 17th century) is closely related. Versed (early 17th century), as in well versed in, is different, coming from Latin versari ‘be engaged in’.

Rhymes
