Generation and reversal of surface flows by propagating waves

Punzmann, Horst; Francois, Nicolas; Xia, Hua; Falkovich, Gregory; Shats, Michael

Description

The ability to send a wave to fetch an object from a distance would find a broad range of applications. Quasi-standing Faraday waves on water create horizontal vortices, yet it is not known whether propagating waves can generate large-scale flows-small-amplitude irrotational waves only push particles in the direction of propagation. Here we show that when waves become three-dimensional as a result of the modulation instability, a floater can be forced to move towards the wave source. The...[Show more]
