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...

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...

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

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

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

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...

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...

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...

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...

Boundary-Layer Meteorology is a monthly peer-reviewed scientific journal published by Springer Science+Business Media. It was established in 1970 by R...

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

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

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...

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...

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

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

separate cases of top and bottom boundary layers are shown below. We will consider boundary conditions of the Ekman layer in the upper ocean: at  z = 0 :...

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

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...

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

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...

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...

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

boundary layer is used in meteorology and physical oceanography. The atmospheric surface layer is the lowest part of the atmospheric boundary layer (typically...

to include the tendency of any fluid boundary layer to adhere to a curved surface, not just the boundary layer accompanying a fluid jet. It is in this...

In astronomy, CENBOL (derived from "CENtrifugal pressure supported BOundary Layer) is a model developed by the astrophysicist Sandip Chakrabarti and collaborators...

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

inside a convection boundary layer. It is calculated as the arithmetic mean of the temperature at the surface of the solid boundary wall (Tw) and the free-stream...

velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe. A similar effect...

consideration of the geometric similarity of the momentum boundary layer and the thermal boundary layer, where it can be used to express a relationship between...
