Stability of a liquid layer draining around a horizontal cylinder: Interplay of capillary and gravity forces
François Gallaire, Shahab Eghbali, Simeon Vladimirov Djambov
We study the drainage of a viscous liquid film coating the outside of a solid horizontal cylinder, where gravity acts vertically. We focus on the limit of large Ohnesorge numbers Oh, where inertia is negligible compared to viscous effects. We first study t ...
Amer Physical Soc2024Electric-field-induced second-order nonlinear processes in stoichiometric silicon nitride
Nonlinear optical frequency conversion is one of the driving research areas in photonics. Its quasi instantaneous response and the promise of low power consumption in integrated structures could cover the demand for fast signal processing with minimal ener ...
EPFL2024Non-contact robotic manipulation of floating objects: exploiting emergent limit cycles
Josephine Anna Eleanor Hughes, Nana Obayashi
The study of non-contact manipulation in water, and the ability to robotically control floating objects has gained recent attention due to wide-ranging potential applications, including the analysis of plastic pollution in the oceans and the optimization o ...
Lausanne2023Columnlike free-interface flows: symmetry breaking and linear instability
This thesis is dedicated to the analysis of a subclass of interfacial flows, columnlike free-interface flows, from two view angles: (i) the symmetry breaking under geometry-induced or external forces, (ii) their stability against infinitesimal disturbances ...
EPFL2023Mean flow modeling in high-order nonlinear Schrodinger equations
The evaluation and consideration of the mean flow in wave evolution equations are necessary for the accurate prediction of fluid particle trajectories under wave groups, with relevant implications in several domains, from the transport of pollutants in the ...
2023Application of ray methods to one-dimensional site response of inhomogeneous soil deposits
The technique referred as ray approximation treats wave propagation in a heterogeneous medium at the infinitely small wavelength limit. This classic simplification allows useful approximate analytical results to be obtained in cases where complete descript ...
2022Zero dispersion Kerr solitons in optical microresonators
Tobias Kippenberg, Junqiu Liu, Wenle Weng, Miles Henry Anderson, Alexey Tikan
Solitons are shape preserving waveforms that are ubiquitous across nonlinear dynamical systems from BEC to hydrodynamics, and fall into two separate classes: bright solitons existing in anomalous group velocity dispersion, and switching waves forming 'dark ...
NATURE PORTFOLIO2022The effect of natural surfactants on air-water momentum exchange under light wind conditions in Lake Geneva
David Andrew Barry, Ulrich Lemmin, Mehrshad Foroughan
Randomly distributed patches of smooth or rough/rippled surfaces are readily observed on most water bodies. Smooth surface patches are called natural slicks and typically form under low wind conditions (< 6 m s-1) when biogenic surfactants in the surface m ...
2022Relaxation of capillary-gravity waves due to contact line nonlinearity: A projection method
François Gallaire, Alessandro Bongarzone, Francesco Viola
We present a physics-inspired mathematical model based on successive linear eigenmode projections to solve the relaxation of small-amplitude and two-dimensional viscous capillary-gravity waves with a phenomenological nonlinear contact line model. We show t ...
AIP Publishing2021Decadal shoreline erosion and recovery of beaches in modified and natural estuaries
Sandy beaches in estuaries and bays (BEBs) are common landforms on the coasts of many major cities. They exist under a wide range of settings and their morphology is controlled by their distance from the estuary/bay entrance, exposure to different types of ...
