Nonlinear synthetic Schlieren methods for free-surface topography measurement using telecentric imaging
Shimin Zhang, Frédéric Moisy, Wietze Herreman +1
Free-surface synthetic Schlieren (FS-SS) is a high-resolution, refraction-based optical technique for measuring the instantaneous elevation of a liquid interface. Under the assumpt…
Capillary effects on preferential orientation of floaters in gravity waves
Basile Dhote, Ewen Le Ster, Wietze Herreman +1
We study the influence of capillary effects on the motion of thin elastic plates denser than water drifting in propagating surface gravity waves. Such floaters experience a mean an…
Preferential orientation of slender elastic floaters in gravity waves
Wietze Herreman, Basile Dhote, Frederic Moisy
Slender floaters drifting in propagating gravity waves slowly rotate towards a preferential state of orientation with respect to the angle of incidence. This angular drift arises f…
Flexible floaters align with the direction of wave propagation
Basile Dhote, Frederic Moisy, Wietze Herreman
We investigate the slow, second order motion of thin flexible floating strips drifting in surface gravity waves. We introduce a diffractionless model (Froude-Krylov approximation)…
