Related to Boundary layers: Turbulent 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.

He weaves through this a parallel story of beginning to see boundary layers not just between objects but between concepts, such as biogeoclimatic zones, species and ecosystem, European and North American ecological mindsets, nature and culture, and finally and most fundamentally for him, science and humanities.
These vortices are formed by flow separations, for which the longitudinal coherent vortices inside turbulent boundary layers on vehicle surfaces are presumably playing an important role.

By extending the fine mesh from the boundary layers along cut planes through the domain, a large variation from one cell size to the neighboring cell size occurs along those planes.
Since the aerodynamic performance of compressor grids is mostly defined by the processes that occur at the boundary layers on blades, there is great interest in considering the influence of periodic flow non-uniformity in front of grids on the compressor grids streamlining and flow at the boundary layer on blades (Schlichting 1969; Liblein, Randebuseh 1956).
To have a direct comparison against flashback limits from the literature, which were almost exclusively recorded for zero pressure-gradient boundary layers of tube burners, the lower wall of the rectangular duct was adjusted horizontal, such that a straight channel could be investigated.
Turbulent boundary layers undergoing pressure gradient are frequently encountered in industrial applications like aeronautics, turbomachinery, etc.
