boundary layer — n. a very thin layer of fluid immediately next to a solid body, that flows more slowly than the rest of the fluid … English World 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 — Physics. the portion of a fluid flowing past a body that is in the immediate vicinity of the body and that has a reduced flow due to the forces of adhesion and viscosity. [1920 25] * * * In fluid mechanics, a thin layer of flowing gas or liquid… … Universalium
boundary layer — The layer of fluid, close to the surface of a body placed in a moving stream, in which the impact pressure is reduced as a result of the viscosity of the fluid. A velocity gradient exists through the boundary layer, ranging from the velocity of… … Aviation dictionary

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
Boundary-layer thickness — This page describes some parameters used to measure the properties of boundary layers. Consider a stationary body with a turbulent flow moving around it, like the semi infinite flat plate with air flowing over the top of the plate. At the solid… … Wikipedia
Boundary layer transition — The process of a laminar boundary layer becoming turbulent is known as boundary layer transition. This process is an extraordinarily complicated process which at present is not fully understood. However, as the result of many decades of intensive … Wikipedia
