Rotation of an immersed cylinder sliding near a thin elastic coating
Bhargav Rallabandi, Baudouin Saintyves, Theo Jules +4
It is known that an object translating parallel to a soft wall in a viscous fluid produces hydro- dynamic stresses that deform the wall, which, in turn, results in a lift force on…
Elastohydrodynamic wake and wave resistance
Maxence Arutkin, René Ledesma-Alonso, Thomas Salez +1
The dynamics of a thin elastic sheet lubricated by a narrow layer of liquid is relevant to various situations and length scales. In the continuity of our previous work on viscous w…
The chaotic dynamics of large-scale structures in a turbulent wake
Eliott Varon, Yoann Eulalie, Stephie Edwige +2
The dynamics of a 3D bimodal turbulent wake downstream a square-back Ahmed body are experimentally studied in a wind-tunnel through high-frequency wall pressure probes mapping the…
Pilot-wave dynamics in a harmonic potential: Quantization and stability of circular orbits
Matthieu Labousse, Anand U. Oza, Stéhane Perrard +1
We present the results of a theoretical investigation of the dynamics of a droplet walking on a vibrating fluid bath under the influence of a harmonic potential. The walking drople…
Predicting the size of droplets produced through Laplace pressure induced snap-off
Solomon Barkley, Samantha J. Scarfe, Eric R. Weeks +1
Laplace pressure driven snap-off is a technique that is used to produce droplets for emulsions and microfluidics purposes. Previous predictions of droplet size have assumed a quasi…
Time-Reversal of Nonlinear Waves - Applicability and Limitations
G. Ducrozet, M. Fink, A. Chabchoub
Time-reversal (TR) refocusing of waves is one of fundamental principles in wave physics. Using the TR approach, "Time-reversal mirrors" can physically create a time-reversed wave t…
