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.
The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. The gas emerging from the hot end can reach temperatures of 200 °C (390 °F), and the gas emerging from the cold end can reach −50 °C (−60 °F). [ 1 ]
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 .

To manage safety and wear of the arena (2), the planned maximum speed of the vortex base (33) is near 3 m/s (10 ft/s). The resulting vortex should resemble a large, slow dust-devil of water-mist more than a violent tornado. In uninhabited areas, faster speeds might be permitted so the vortex can survive in faster ambient winds.
Many high-performance aircraft use the dogtooth design, which induces a vortex over the wing to control boundary layer spanwise extension, increasing lift and improving resistance to stall. Some of the best-known uses of the dogtooth are in the stabilizer of the F-15 Eagle and the wings of the F-4 Phantom II , F/A-18 Super Hornet , CF-105 Arrow ...
The aircraft was returned to Red Lion before being hauled back to NAFEC on February 24, 1971, following the fitting of vortex generators and the third propeller. [20] Tests resumed at NAFEC on March 1, 1971. [21] On this occasion, the 26 "went up and out of ground effect with no strain at all". [22]
