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 basic problems of transition in both incompressible and compressible boundary layers
are reviewed. Flow structures in low-speed transitional and developed turbulent boundary …

This article provides theoretical conditions for the use and meaning of a stability analysis
around a mean flow. As such, it may be considered as an extension of the works by McKeon …

In this paper, we address the problem of how to account for second-order statistics of
turbulent flows using low-complexity stochastic dynamical models based on the linearized …

Direct numerical simulations for fully developed channel flow, subjected to oscillatory
spanwise wall motion, have been performed and analysed in an effort to illuminate the …

The influence of near-wall density and viscosity gradients on near-wall turbulence in a
channel is studied by means of direct numerical simulation of the low-Mach-number …

It has been recently shown that the energy-containing motions (ie coherent structures) in
turbulent channel flow exist in the form of Townsend's attached eddies by a numerical …

A spatially developing supersonic boundary layer at Mach 2 is analysed by means of direct
numerical simulation of the compressible Navier--Stokes equations, with the objective of …

Despite a growing body of recent evidence on the hierarchical organization of the self-
similar energy-containing motions in the form of Townsend's attached eddies in wall …

The efficiency of transfer of gases and particles across the air-sea interface is controlled by
several physical, biological and chemical processes in the atmosphere and water which are …
