Preferential orientation of slender elastic floaters in gravity waves

Basile Dhote, Frederic Moisy, Wietze Herreman

Slender elastic floaters in gravity waves rotate to align either along or across the wave direction depending on their stiffness, length and mass.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

For floater lengths smaller than half the wavelength, soft, short and heavy floaters prefer the longitudinal state, while stiff, long and light floaters prefer the transverse state.

C2weakest assumption

The diffractionless hydro-elastic theory assumes the floater width and thickness are small compared with the wavelength and that the structure remains thin and flexible.

C3one line summary

Slender floaters in gravity waves prefer longitudinal orientation if soft, short and heavy or transverse if stiff, long and light due to a second-order mean yaw moment.
