Since the introduction of the logarithmic law of the wall more than 80 years ago, the equation for the mean velocity profile in turbulent boundary layers has been widely applied to model near-surface processes and parameterize surface drag. Yet the hypothetical turbulent eddies proposed in the original logarithmic law derivation and mixing length theory of Prandtl have never been conclusively linked to physical features in the flow. Here, we present evidence that suggests these eddies… 
Self-similar geometries within the inertial subrange of scales in boundary layer turbulence
Abstract The inertial subrange of turbulent scales is commonly reflected by a power law signature in ensemble statistics such as the energy spectrum and structure functions – both in theory and from
Turbulence organization and mean profile shapes in the stably stratified boundary layer: zones of uniform momentum and air temperature
A persistent spatial organization of eddies is identified in the lowest portion of the stably-stratified planetary boundary layer. The analysis uses flow realizations from published large-eddy
Prograde vortices, internal shear layers and the Taylor microscale in high-Reynolds-number turbulent boundary layers
Abstract The statistical properties of prograde spanwise vortex cores and internal shear layers (ISLs) are evaluated for a series of high-Reynolds-number turbulent boundary layers. The considered
Uniform momentum zone scaling arguments from direct numerical simulation of inertia-dominated channel turbulence
Abstract Inertia-dominated wall-sheared turbulent flows are composed of an inner and outer layer, where the former is occupied by the well-known autonomous inner cycle while the latter is composed of
Evidence that uniform momentum zones originate from roughness sublayer structure interactions in fully rough channel turbulence
Abstract Fully rough wall-sheared turbulence is composed of an inner and outer layer, the former occupied by sinuous structures sustained by the well-known autonomous inner cycle, the latter occupied
Generation and characterization of fully developed state in open channel flow
Abstract A fully developed approach flow is necessary in open channel studies to maintain commonality among datasets obtained from different facilities. Two-component planar particle image
Characterization of atmospheric coherent structures and their impact on a utility-scale wind turbine
Abstract Atmospheric turbulent velocity fluctuations are known to increase wind turbine structural loading and accelerate wake recovery, but the impact of vortical coherent structures in the

Vortex organization in the outer region of the turbulent boundary layer
The structure of energy-containing turbulence in the outer region of a zero-pressure- gradient boundary layer has been studied using particle image velocimetry (PIV) to measure the instantaneous
The spatial structure of the logarithmic region in very-high-Reynolds-number rough wall turbulent boundary layers
Using super-large-scale particle image velocimetry (SLPIV), we investigate the spatial structure of the near-wall region in the fully rough atmospheric surface layer with Reynolds number
A uniform momentum zone–vortical fissure model of the turbulent boundary layer
Recent studies reveal that at large friction Reynolds number $\unicode[STIX]{x1D6FF}^{+}$ the inertially dominated region of the turbulent boundary layer is composed of large-scale zones of nearly
Interfaces and internal layers in a turbulent boundary layer
New experimental research is presented on the characteristics of interfaces and internal shear layers that are present in a turbulent boundary layer (TBL). The turbulent/non-turbulent (T/NT)

Interfaces of uniform momentum zones in turbulent boundary layers
In this paper we examine the characteristics of the interfaces that demarcate regions of relatively uniform streamwise momentum in turbulent boundary layers. The analysis utilises particle image
