Wall-bounded turbulence exhibits patterns that persist in time and space: coherent
structures. These are important for transport processes and form a conceptual framework for …

The inherent difficulty of understanding turbulence has led to researchers attacking the topic
in many different ways over the years of turbulence research. Some approaches have been …

Two-point statistics are presented for a new direct simulation of the zero-pressure-gradient
turbulent boundary layer in the range Re θ= 2780–6680, and compared with channels in the …

The transport equations for the variances of the velocity components are investigated using
data from direct numerical simulations of incompressible channel flows at friction Reynolds …

Structural properties of regions of uniform streamwise momentum in turbulent boundary
layers are examined using experimental databases obtained from particle image …

Wall turbulence is a ubiquitous phenomenon in nature and engineering applications, yet
predicting such turbulence is difficult due to its complexity. High-Reynolds-number …

A direct numerical simulation of a turbulent pipe flow at a high Reynolds number of Reτ=
3008 over a long axial domain length (30R) was performed. The streamwise mean velocity …

Direct numerical simulation data of turbulent channel flow ($ Re_ {{\it\tau}}= 930$) are used
to investigate the statistics of long motions of streamwise velocity fluctuations ($ u $), and the …
