Liquid interface shaping and transport phenomena induced by spatially inhomogeneous vibrations
Benjamin Apffel, Christian Wilkinson, Emmanuel Fort
Vibrations can dynamically stabilize otherwise unstable liquid interfaces and produce new dynamic equilibria, called vibro-equilibria. Typically, the vibrations are homogeneous in…
Formation and dynamics of a semi vortex ring connected to a free surface
Alexandre Vilquin, Samuel Hidalgo-Caballero, Vincent Pagneux +2
Playing a role in the locomotion of some animals such as the water strider, the formation and dynamics of a semi vortex ring connected to a free surface are experimentally investig…
Space-time resolved measurements of the effect of pinned contact line on the dispersion relation of water waves
Eduardo Monsalve, Agnès Maurel, Vincent Pagneux +1
We report on an experimental investigation of the propagation of gravity-capillary waves in a narrow channel with a pinned contact line. By using Fourier Transform Profilometry (FT…
Dynamics of heavy and buoyant underwater pendulums
Varghese Mathai, Laura Loeffen, Timothy Chan +1
The humble pendulum is often invoked as the archetype of a simple, gravity driven, oscillator. Under ideal circumstances, the oscillation frequency of the pendulum is independent o…
The hydraulic bump: The surface signature of a plunging jet
Matthieu Labousse, John W. M. Bush
When a falling jet of fluid strikes a horizontal fluid layer, a hydraulic jump arises downstream of the point of impact provided a critical flow rate is exceeded. We here examine a…
Mutual adaptation of a Faraday instability pattern with its flexible boundaries in floating fluid drops
Giuseppe Pucci, Emmanuel Fort, Martine Ben Amar +1
Hydrodynamic instabilities are usually investigated in confined geometries where the resulting spatiotemporal pattern is constrained by the boundary conditions. Here we study the F…
