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 — 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 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 — 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 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
boundary-layer normal-pressure drag — A drag resulting from the shape of the body. Streamlining the exposed parts can reduce boundary layer drag. See also form drag … Aviation dictionary
Blasius boundary layer — A Blasius boundary layer, in physics and fluid mechanics, describes the steady two dimensional boundary layer that forms on a semi infinite plate which is held parallel to a constant unidirectional flow U.Within the boundary layer the usual… … Wikipedia
Diffusion boundary layer — The diffusion boundary layer is a thin (usually on the scale of micrometers) layer of fluid which is not mixed with the main body of the fluid (or cellular arrangement in the case of organisms), by virtue of its proximity to the fluid s edge. In… … Wikipedia
boundary layer — /ˈbaʊndri leɪə/ (say bowndree layuh) noun Aeronautics, Physics, etc. the thin layer of fluid next to the surface of a moving body in which there is a transition between the velocity of the body on one side, and the velocity of the fluid on the… …
