English

Subject field(s)
  • Aircraft Airframe
  • Ship and Boat Parts
DEF

A device, often a small vane attached to a surface, to produce one or more discrete vortices which trail downstream adjacent to the surface, promote mixing in the boundary layer and delay boundary-layer separation.

OBS

vortex generator: designation and definition standardized by the British Standards Institution (BSI).

Record 2 2012-07-22

English

Subject field(s)
  • Electric Rotary Machines
  • Wind Energy
  • Mechanical Construction
DEF

[A] small mechanical device which is attached to the suction surface of [a] stall-regulated blade which generates local vortices.

CONT

The vortex generator has been proposed in the form of specially designed buildings, towers, baffles and a variety of other structures that spin the wind stream, thus creating strong vortexing at the wind turbine.

OBS

These vortices re-energise the boundary layer and hence prevent stall. When viewed from above they are often V-shaped with the sharp end of the V pointing towards the leading edge.

French

Domaine(s)
  • Machines tournantes électriques
  • Énergie éolienne
  • Construction mécanique
DEF

Petit appareil mécanique fixé à une pale à régulation par décrochage aérodynamique qui produit des tourbillons (vortex).

CONT

La Grumman Aérospace Corporation étudie une installation d'un type particulier réunissant une éolienne classique avec un générateur à vortex. Le générateur à vortex permet d'augmenter la dépression à l'aval de l'éolienne et, par voie de conséquence, la vitesse du vent à la traversée de celle-ci et donc la puissance produite.

Spanish

Campo(s) temático(s)
  • Máquinas rotativas eléctricas
