In physics and fluid mechanics, a boundary layer is the thin layer of fluid in the immediate vicinity of a bounding surface formed by the fluid flowing...

mechanics, a Blasius boundary layer (named after Paul Richard Heinrich Blasius) describes the steady two-dimensional laminar boundary layer that forms on a...

thickness and shape of boundary layers formed by fluid flowing along a solid surface. The defining characteristic of boundary layer flow is that at the solid...

500–1,800 K hotter than the overlying mantle, creating a thermal boundary layer. The boundary is thought to harbor topography, much like Earth's surface, that...

In engineering, boundary layer control refers to methods of controlling the behaviour of fluid flow boundary layers. It may be desirable to reduce flow...

In meteorology, the planetary boundary layer (PBL), also known as the atmospheric boundary layer (ABL) or peplosphere, is the lowest part of the atmosphere...

flow separation or boundary layer separation is the detachment of a boundary layer from a surface into a wake. A boundary layer exists whenever there...

Falkner–Skan boundary layer (named after Victor Montague Falkner and Sylvia W. Skan) describes the steady two-dimensional laminar boundary layer that forms...

thermal boundary layer formed by a heated (or cooled) fluid moving along a heated (or cooled) wall. In many ways, the thermal boundary layer description...

applies to any fluid flow, and is most often used in the context of boundary layers. In 1883 Osborne Reynolds demonstrated the transition to turbulent...

Vaughn Michel discovered that sedimentary layers found all over the world at the Cretaceous–Paleogene boundary contain a concentration of iridium hundreds...

instruments can be used to measure properties of the planetary boundary layer, including boundary layer height, aerosols and clouds. Satellite remote sensing of...

layers of the decidua basalis can then be described: Compact outer layer (stratum compactum) Intermediate layer (stratum spongiosum) Boundary layer adjacent...

The benthic boundary layer (BBL) is the layer of water directly above the sediment at the bottom of a body of water (river, lake, or sea, etc.). Through...

transition layers in general, and specifically as boundary layers or interior layers depending on whether they occur at the domain boundary (as is the...

broader category known as powered lift, which also includes various boundary layer control systems, systems using directed prop wash, and circulation control...

Boundary layer suction is a boundary layer control technique in which an air pump is used to extract the boundary layer at the wing or the inlet of an...

Stokes second problem or sometimes referred to as Stokes boundary layer or Oscillating boundary layer is a problem of determining the flow created by an oscillating...

wing, the splitter plate diverts the boundary layer away from the engine intake. It is a form of boundary layer control. When a body, such as a wing or...

lithosphere–asthenosphere boundary (referred to as the LAB by geophysicists) represents a mechanical difference between layers in Earth's inner structure...

The atmosphere of Earth consists of a layer of mixed gas that is retained by gravity, surrounding the Earth's surface. Known collectively as air, it contains...

boundary layer, called boundary-layer theory; while the flow outside the boundary layer could be treated using inviscid flow theory. Boundary-layer theory...

For example, in a fully developed turbulent channel flow or turbulent boundary layer, the streamwise momentum equation in the very near wall region reduces...

less than the boundary layer thickness then the boundary layer will not separate and vortices will not form. However, when the boundary layer does grow beyond...

up to and including transonic velocities. His studies identified the boundary layer, thin-airfoils, and lifting-line theories. The Prandtl number was named...

described the boundary layer and its importance for drag and streamlining. The paper also described flow separation as a result of the boundary layer. He discovered...
