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.

The Parcel Boundary Layer Will Be The Base Layer To Build New Data Layers And Correct Other
The aim of this study is to investigate, the effect of physical parameters on boundary layer flow of nanofluids over a flat plate.
The occurrence of the boundary layer separation greatly reduces the effective smoke exhausting area of the vertical shaft and the natural ventilation effectiveness.
In the present paper, the two-dimensional steadystate boundary layer flow of nanofluids over an impermeable semi-infinite moving flat horizontal plate embedded in the water-based nanofluid is studied.
This mesh distribution led to numerical errors occurring when the boundary layer cells were smaller than 0.
Robertson of University of Colorado, Boulder, Colorado, USA, and his team showed that the apparent lack of charcoal in the K-Pg boundary layer resulted from changes in sedimentation rates: When the charcoal data are corrected for the known changes in sedimentation rates, they exhibit an excess of charcoal, not a deficiency.
Danberg and Fansler [4] investigated the non similar solution for the flow in the boundary layer past a wall that is stretched with a velocity proportional to the distance along the wall.
It stipulates the inertness of transient processes in the boundary layer and the possibility of the occurrence of hysteresis at the process of plate streamlining by the periodically non-uniform flow.
The interest in understanding turbulent boundary layer flows with pressure gradients also stems from the requirement to model such flows.
The difference in temperatures of heated surface and flowing air creates a temperature boundary layer near the plate surface, where the temperature changes in a direction vertical to the surface.
SST (shear stress transport) turbulence model has high accuracy and better algorithm stability in boundary layer simulation and also gives a highly accurate predictions of the onset and the amount of flow separation(LU, 2004; Ball, 2001).
The study of thermal boundary layer problem for two-dimensional steady and incompressible laminar flow past a wedge has received considerable interest in the field of aerodynamics.
