Numerical Simulation of Collinear Capillary-Wave Turbulence
Evgeny Kochurin, Guillaume Ricard, Nikolay Zubarev +1
We report on direct numerical simulation of quasi-one-dimensional bidirectional capillary-wave turbulence. Although nontrivial three-wave and four-wave resonant interactions are ab…
Streamwise Dissolution Patterns Created by a Flowing Water Film
Adrien Guérin, Julien Derr, Sylvain Courrech du Pont +1
The dissolution of rocks by rainfall commonly generates streamwise parallel channels, yet the occurrence of these natural patterns remains to be understood. Here, we report the eme…
The charmed string: self-supporting loops through air drag
Adrian Daerr, Juliette Courson, Margaux Abello +2
The string shooter experiment uses counter-rotating pulleys to propel a closed string forward. Its steady state exhibits a transition from a gravity dominated regime at low velocit…
Saturation of the inverse cascade in surface gravity wave turbulence
Eric Falcon, Guillaume Michel, Gaurav Prabhudesai +5
We report on the observation of surface gravity wave turbulence at scales larger than the forcing ones in a large basin. In addition to the downscale transfer usually reported in g…
Buoyancy driven dissolution of inclined blocks: Erosion rate and pattern formation
Caroline Cohen, Michael Berhanu, Julien Derr +1
The dissolution of a body into quiescent water leads to density stratifications at the interfaces that drive buoyant flows. Where the stratification is unstable, the flow destabili…
Unveiling of the mechanisms of acoustic streaming induced by sharp edges
Chuanyu Zhang, Xiaofeng Guo, Laurent Royon +1
Acoustic waves can generate steady streaming within a fluid owing to the generation of viscous boundary layers near walls, of typical thickness . In microchannels, the acoustic…
