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 fence — A device to prevent, or at least delay, the boundary layer separation. Shallow fences are fixed axially across the wing to reduce or check spanwise drift of the boundary layer and its consequent thickening and tendency for separation … Aviation dictionary
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
Shape factor (boundary layer flow) — A shape factor is used in boundary layer flow to determine the nature of the flow.:H= frac {delta^*}{ heta}where H is the shape factor, delta^* is the displacement thickness and θ is the momentum thickness. Displacement thickness is defined as… … Wikipedia
Stokes boundary layer — in a viscous fluid due to the harmonic oscillation of a plane rigid plate. Velocity (blue line) and particle excursion (red dots) as a function of the distance to the wall. In fluid dynamics, the Stokes boundary layer, or oscillatory boundary… … Wikipedia
Separation — may refer to several different subjects: *Separation processes, in chemistry *Flow separation, separation of a fluid boundary layer from the surface of a solid body moving relative to the fluid *Legal separation, a legal status where married… … Wikipedia
separation point — The position at which the boundary layer leaves the surface of a solid body. It may occur with the laminar flow (laminar separation) or when the boundary layer is turbulent (turbulent separation). Separation is sometimes followed by reattachment… … Aviation dictionary
separation — noun 1》 the action or state of separating or being separated. ↘the state in which a husband and wife remain married but live apart: a trial separation. 2》 distinction between the signals carried by the two channels of a stereophonic system.… … English new terms 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
