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.

In the microenvironment we are testing, tracer gas transport is dominated by interaction among the periodical exhalation airflows from the manikins, as well as their thermal convective boundary layers.
The inhalation air mostly draws from the air contained in the body's thermal convective boundary layer (if it is not disturbed).
PECAN data show that pristine nocturnal CI above a SBL is not uncommon, but such elevated CI is more obscure than CI in a surface-based convective boundary layer, and its precursors are more difficult to measure.
This is a relatively small value and it means the partition coefficient is not sensitive to the convective boundary layer resistance.
Whilst the convective boundary layer (CBL) is relatively insensitive to even moderate scale topography (Kaimal et al.
