The availability of new optical and electronic components and the increasing demands on
measurement accuracy have led to a continuous development of the laser Doppler …

The shear layer that develops at the interface between converging flows is a prominent but
poorly understood hydrodynamic feature at stream confluences. To examine the spatial and …

Direct numerical simulations of turbulent channel flow at Re τ= 205 and 932 have been
carried out to examine Taylor's “frozen turbulence” hypothesis. The terms in Taylor's …

Two-point measurements of the streamwise velocity in a turbulent channel flow are
performed using laser-Doppler anemometry. High spatial and temporal resolutions (about 1 …

The spatial structure of smooth-and rough-wall boundary layers is examined spectrally at
approximately matched friction Reynolds number (). For each wall condition, temporal and …

A combined wind tunnel and computational study of grid-generated turbulence along the
centreline shows that the close to− 5/3 power law signature of energy spectra in the …

This paper investigates the processes and spatial patterns of the turbulent flow around a
naturally formed in situ pebble cluster and the interactions with large‐scale coherent flow …

Spatial turbulence spectra for high-Reynolds-number shear flows are usually obtained by
mapping experimental frequency spectra into wavenumber space using Taylor's hypothesis …

The motion tracking enhancement technique (MTE) is a recently introduced method to
improve the accuracy of tomographic PIV measurements at seeding density higher than …

We study the application of Taylor's frozen hypothesis to the pressure fluctuations in
turbulent channels by means of spatio-temporal data from direct numerical simulations with …
