Boundary layer
In
physics
and
fluid mechanics
, a
boundary layer
is the layer of
fluid
in the immediate vicinity of a
bounding surface
where the effects of viscosity are significant. In the
Earth's atmosphere
, the
atmospheric boundary layer
is the air layer near the ground affected by diurnal heat, moisture or momentum transfer to or from the surface. On an
aircraft
wing
the boundary layer is the part of the flow close to the wing, where
viscous
forces
distort the surrounding non-viscous flow. See
Reynolds number
.
