1958
Two experimental studies of turbulent boundary layers are described. The first was begun as part of a search for more accurate knowledge of the structure and motion of the large-scale eddy motions that appear to control the rate of entrainment of non-turbulent fluid and which may also play a dominant part in the constant-stress layer.

Quite often turbulent boundary layer theory is introduced by the statement, that turbulent boundary layers are governed by the same equations as the laminar boundary layers, except the kinematic viscosity v and thermal diffusivity a have to be replaced by the so—called effective kinematic viscosity v eff and effective thermal diffusivity a eff ...

The Development of Turbulent Boundary Layers
Journal of the Aeronautical Sciences, 1956The structure of several recently measured sets of velocity profiles in quasi-two-dimensional turbulent boundary layers is examined. I t is shown that the inner one-fifth of each profile is well represented, independently of pressure gradient, by the universal logarithmic law that was observed by Ludwieg and Tillmann.

Unsteady Turbulent Boundary Layers.
1983Abstract : A comprehensive study of periodic turbulent boundary layers and pipe flows has been completed. The study has resulted in the identification of the various operating regimes of these flows and the appropriate parameters to characterize them.

Turbulence in the Atmospheric Boundary Layer
The Physics of Fluids, 1967The specific features of atmospheric boundary-layer turbulence are described. The small-scale properties of atmospheric turbulence depend very little on the peculiarities of its large-scale components and obey approximately the laws of locally isotropic turbulence. It is shown that turbulence is locally axisymmetric in respect to the vertical direction
