Vortex — A vortex (pl. vortices ) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the… … Wikipedia
Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… … Wikipedia
Vortex shedding — is an unsteady flow that takes place in special flow velocities (according to the size and shape of the cylindrical body). In this flow, vortices are created at the back of the body and detach periodically from either side of the body. See Von… … Wikipedia
Vortex induced vibration — Vortex induced vibrations (VIV) are motions induced on bodies facing an external flow by periodical irregularities on this flow. The classical example is the VIV of an underwater cylinder. You can see how this happens by putting a cylinder into… … Wikipedia
Vortex lattice method — The Vortex lattice method, (VLM), is a numerical, Computational fluid dynamics, method used mainly in the early stages of aircraft design and in aerodynamic education at university level. The VLM models the lifting surfaces, such as a wing, of an … Wikipedia
Vortex ring — A vortex ring, also called a toroidal vortex, is a region of rotating fluid moving through the same or different fluid where the flow pattern takes on a doughnut shape. The movement of the fluid is about the poloidal or circular axis of the… … Wikipedia
Vortex engine — The concept of a Vortex Engine, independently proposed by Norman Louat [Louat s International Patent Application is PCT/AU99/00037] and Louis Michaud [Michaud s U.S. Patent is US 2004/0112055 A1, Atmospheric Vortex Engine ] , aims to replace… … Wikipedia
Vortex tube — For the term vortex tube used in fluid dynamics please see: vorticity 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. It has no moving parts.… … Wikipedia
Vortex dynamics — In 1858 Hermann von Helmholtz published his seminal paper entitled Über Integrale der hydrodynamischen Gleichungen, welche den Wirbelbewegungen entsprechen, in Journal für die reine und angewandte Mathematik , vol. 55, pp.25 55. So important was… … Wikipedia
vortex — i. In meteorology, any rotary flow in the atmosphere. ii. As used in aerodynamics, circular patterns of air created by the movement of an airfoil through the air when generating lift. As an airfoil moves through the atmosphere in sustained flight … Aviation dictionary
Flow separation — All solid objects travelling through a fluid (or alternatively a stationary object exposed to a moving fluid) acquire a boundary layer of fluid around them where viscous forces occur in the layer of fluid close to the solid surface. Boundary… … Wikipedia
