Surface roughness can significantly influence the fluid dynamics and heat transfer in
convective flows by inducing perturbations in the velocity profile which affect surface drag …

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

Data-driven methods have become an essential part of the methodological portfolio of fluid
dynamicists, motivating students and practitioners to gather practical knowledge from a …

The present review shows a summary of current trends in high-fidelity simulations of
turbulent flows in moderately complex geometries. These trends are put in the historical …

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 …

Non-equilibrium wall turbulence with mean-flow three-dimensionality is ubiquitous in
geophysical and engineering flows. Under these conditions, turbulence may experience a …

Wall-attached structures of streamwise velocity fluctuations in an adverse-pressure-gradient
turbulent boundary layer Page 1 J. Fluid Mech. (2020), vol. 885, A12. c Cambridge University …

Turbulent flows in the presence of walls may be apprehended as a collection of momentum-
and energy-containing eddies (energy-eddies), whose sizes differ by many orders of …

Bidimensional empirical mode decomposition (BEMD) is used to identify attached eddies in
turbulent channel flows and quantify their relationship with the mean skin-friction drag …
