Particle image velocimetry (PIV) has become the chief experimental technique for velocity
field measurements in fluid flows. The technique yields quantitative visualizations of the …

We depict and analyse the complete evolution of an air bubble formed in a water bulk, from
the time it emerges at the liquid surface, up to its fragmentation into dispersed drops. To this …

Image deformation methods in particle image velocimetry are becoming more and more
accepted by the scientific community but some aspects have not been thoroughly …

A quantitative synthetic Schlieren imaging (SSI) method based on fast Fourier demodulation
is presented. Instead of a random dot pattern (as usually employed in SSI), a 2D periodic …

In the gravity field, density changes triggered by a kinetic scheme as simple as A+ B→ C can
induce or affect buoyancy-driven instabilities at a horizontal interface between two solutions …

Particle image velocimetry (PIV) measurements were performed in a wave tank under water
waves propagating and breaking on a 1/15 sloping beach. The wave transformation …

The uncertainty quantification of particle image velocimetry (PIV) measurements has
recently become a topic of great interest as shown by the recent appearance of several …

We investigate the instability of a single helical vortex filament of small pitch with respect to
displacement perturbations whose wavelength is large compared to the vortex core size. We …

Flexibility of marine animal fins has been thought to enhance swimming performance.
However, despite numerous experimental and numerical studies on flapping flexible foils …

A tube filled with a perfectly wetting liquid falls axially under its own weight. In its gravity-free
reference frame, the liquid interface is deformed by surface tension into a hemispherical …
