Wingtip vortices — are tubes of circulating air which are left behind by the wing as it generates lift. One wingtip vortex trails from the tip of each wing. The cores of vortices spin at very high speed and they are regions of very low pressure. The cores of… … Wikipedia
V formation — A V formation (sometimes called a skein) is the symmetric V shaped flight formation of flights of geese, ducks and other migratory birds. V formations are also used on military flight missions.AerodynamicsFlying in a V formation aids the birds in … Wikipedia
Görtler vortices — In fluid dynamics, Görtler vortices are secondary flows that appears in a boundary layer flow along a concave wall. If the boundary layer is thin compared to the radius of curvature of the wall, the pressure remains constant across the boundary… … Wikipedia

Lift-induced drag — In aerodynamics, lift induced drag, induced drag, vortex drag, or sometimes drag due to lift, is a drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting… … Wikipedia

Viscimetry — Viscimation is the turbulence when liquids of different viscosities mix,particularly the formation of vortices (called viscimetric whorls ) and visible separate threads of the different liquids.The term is archaic and idiosyncratic to whisky… … Wikipedia
Vortex power — is a form of hydro power which generates energy by placing obstacles in rivers in order to cause the formation of vortices which can then be tapped for energy.This method is pioneered by a team at the University of Michigan who call the… … Wikipedia
