The kinematics and dynamics of wall-bounded turbulence are surveyed, with emphasis on
the multiscale processes associated with the logarithmic layer and with its interactions with …

Extreme events in fluid flows, waves, or structures interacting with them are critical for a wide
range of areas, including reliability and design in engineering, as well as modeling risk of …

This article discusses the description of wall-bounded turbulence as a deterministic high-
dimensional dynamical system of interacting coherent structures, defined as eddies with …

The effect of domain size on direct numerical simulations of turbulent channels with periodic
boundary conditions is studied. New simulations are presented up to Re τ= 4179 in boxes …

One-point statistics are presented for new direct simulations of the zero-pressure-gradient
turbulent boundary layer in the range Re θ= 2780–6680, matching channels and pipes at …

Known structures and self-sustaining mechanisms of wall turbulence are reviewed and
explored in the context of the scale interactions implied by the nonlinear advective term in …

The high-Reynolds-number behaviour of the canonical incompressible turbulent channel
flow is investigated through large-scale direct numerical simulation (DNS). A Reynolds …

A novel approach to the study of the kinematics and dynamics of turbulent flows is
presented. The method involves tracking in time coherent structures, and provides all of the …
