Water wave interactions with a horizontal submerged elastic plate
Gatien Polly, Alexis Mérigaud, Benjamin Thiria +1
This article explores how a submerged elastic plate, clamped at one edge, interacts with water waves. Submerged elastic plates have been considered as potentially effective design…
On-demand microfluidic droplet pinching and splitting under local confinement gradients
Margaux Kerdraon, Albane Théry, Marc Pascual +2
We report the pinching of an elongated liquid droplet that is confined in a rectangular microchannel. The droplet pinching is induced by a local variation of the channel topography…
Towards High Resolution Real-Time Optical Flow Particle Image Velocimetry
Juan Pimienta, Jean-Luc Aider
Particle Image Velocimetry (PIV) is the most commonly used optical technique for measuring 2D velocity fields. However, improving the spatial resolution of instantaneous velocity f…
Linear stability of turbulent channel flow with one-point closure
P. V. Kashyap, Y. Duguet, O. Dauchot
For low enough flow rates, turbulent channel flow displays spatial modulations of large wavelengths. This phenomenon has recently been interpreted as a linear instability of the tu…
Recovering particle velocity and size distributions in ejecta with Photon Doppler Velocimetry
J. A. Don Jayamanne, R. Outerovitch, F. Ballanger +11
When a solid metal is struck, its free surface can eject fast and fine particles. Despite the many diagnostics that have been implemented to measure the mass, size, velocity or tem…
Regular sloshing modes in irregular cavities using metabathymetry
Adam Anglart, Agnès Maurel, Philippe Petitjeans +1
We present a comprehensive investigation, combining numerical simulations and experimental measurements, into the manipulation of water waves and resonance characteristics within c…
