Related to boundary layer: Atmospheric boundary layer

boundary layer

n.
The layer of reduced velocity in fluids, such as air and water, that is immediately adjacent to the surface of a solid past which the fluid is flowing.

boundary layer

n
(General Physics) the layer of fluid closest to the surface of a solid past which the fluid flows: it has a lower rate of flow than the bulk of the fluid because of its adhesion to the solid

bound′ary lay`er


n.
the region of a fluid flowing in the immediate vicinity of a body, with the flow reduced by adhesion and viscosity.
