A vortex generator (VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface (or airfoil, such as an aircraft wing) [1] or a rotor blade of a wind turbine. [2] VGs may also be attached to some part of an aerodynamic vehicle such as an aircraft fuselage or a car.

A plasma actuator induces a local flow speed perturbation, which will be developed downstream to a vortex sheet. As a result, plasma actuators can behave as vortex generators. The difference between this and traditional vortex generation is that there are no mechanical moving parts or any drilling holes on aerodynamic surfaces, demonstrating an ...

When the speed is reduced and the aircraft approaches stall, the local flow at the leading edge is diverted outwards; this spanwise component of velocity around the vortilon creates a vortex streamed around the top surface, which energises the boundary layer. [6] A more turbulent boundary layer, in turn, delays the local flow separation.
Vortex Bladeless Ltd. is a Spanish technology startup company that is developing a specific type of wind power generator without rotating blades or lubricants. [1] Power is produced from resonant vibrations when wind passes through the turbine and is deflected into vortices in a process called vortex shedding .
Visualisation of the vortex street behind a circular cylinder in air; the flow is made visible through release of glycerol vapour in the air near the cylinder. In fluid dynamics, a Kármán vortex street (or a von Kármán vortex street) is a repeating pattern of swirling vortices, caused by a process known as vortex shedding, which is responsible for the unsteady separation of flow of a fluid ...
