• 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 generator — A vortex generator is an aerodynamic surface, consisting of a small vane that creates a vortex.Peppler, I.L.: From The Ground Up , page 23. Aviation Publishers Co. Limited, Ottawa Ontario, Twenty Seventh Revised Edition, 1996. ISBN 09690054 9 0]… …   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 generator — Small, low aspect ratio airfoils mounted in pairs on the upper surface of the wings of high speed aircraft. These project into the boundary layer and are meant to energize the stagnant boundary layer to promote better flow over the surface and… …   Aviation dictionary

• Boundary layer — For the anatomical structure, see Boundary layer of uterus. Boundary layer visualization, showing transition from laminar to turbulent condition In physics and fluid mechanics, a boundary layer is that layer of fluid in the immediate vicinity of… …   Wikipedia

• Boundary layer separation — is when the thin layer of viscous fluid leaves the surface of the body that it is flowing over. The viscosity of the fluid causes the boundary layer separation. [Wilcox, David C. Basic Fluid Mechanics. 3rd ed. Mill Valley: DCW Industries, Inc.,… …   Wikipedia

• Boundary layer suction — is technique in which an air pump is used to extract the boundary layer at the wing or the inlet of an aircraft. Improving the air flow can reduce drag. Improvements in fuel efficiency have been estimated as high as 30%. The boundary layerThe air …   Wikipedia

• Animal locomotion on the surface layer of water — Animal locomotion on the surface layer is the study of animal locomotion in the case of small animals that live on the surface layer of water, relying on surface tension to stay afloat.There are two means of walking on water; the regime… …   Wikipedia

• edge vortex — An airflow that lies midway between a steady streamline flow and an unsteady flow. The flow separates at sharp leading edges as a result of the boundary layer effect but does not break down into a turbulent airflow. Instead strong vortices are… …   Aviation dictionary
