Signal analysis of an actively generated cavitation bubble in pressurized pipes for detection of wall stiffness drops

Anton Schleiss, Giovanni De Cesare, Mohamed Farhat, Fadi Hachem, Alexandre Jean Pachoud

Due to the increasing production of volatile new renewable energies as solar and wind, storage hydropower plants have to operate under harsh operation conditions in order to stabilize the electricity grid. As a result, highly transient water pressures occu ...

Numerical simulation of a collapsing bubble subject to gravity

Mohamed Farhat, Outi Supponen

The present paper focuses on the simulation of the expansion and aspherical collapse of a laser-generated bubble subjected to an acceleration field and comparison of the results with instances from high-speed videos. The interaction of the liquid and gas i ...

Measurement of the Self-Oscillating Vortex Rope Dynamics for Hydroacoustic Stability Analysis

François Avellan, Sébastien Alligné, Keita Yamamoto

Flow instabilities in hydraulic machines often feature oscillating cavitation volumes, which locally introduce compliance and mass flow gain effects. These unsteady characteristics play a crucial role in one-dimensional stability models and can be determin ...

Herbaceous Angiosperms Are Not More Vulnerable to Drought-Induced Embolism Than Angiosperm Trees

Alexandre Buttler, Hervé Cochard, Constant Signarbieux

The water transport pipeline in herbs is assumed to be more vulnerable to drought than in trees due to the formation of frequent embolisms (gas bubbles), which could be removed by the occurrence of root pressure, especially in grasses. Here, we studied hyd ...

Beer tapping: dynamics of bubbles after impact

François Gallaire, Pierre-Thomas Paul Brun, Vladislav Mantic Lugo

Beer tapping is a well known prank where a bottle of beer is impacted from the top by a solid object, usually another bottle, leading to a sudden foam overflow. A description of the shock-driven bubble dynamics leading to foaming is presented based on an e ...

Detailed Jet Dynamics in a Collapsing Bubble

Mohamed Farhat, Danail Obreschkow, Philipp Kobel, Outi Supponen

We present detailed visualizations of the micro-jet forming inside an aspherically collapsing cavitation bubble near a free surface. The high-quality visualizations of large and strongly deformed bubbles disclose so far unseen features of the dynamics insi ...

Contact angle and adsorption energies of nanoparticles at the air-liquid interface determined by neutron reflectivity and molecular dynamics

Francesco Stellacci, Javier Reguera Gomez, Mauro Moglianetti, Evgeniy Ponomarev

Understanding how nanomaterials interact with interfaces is essential to control their self-assembly as well as their optical, electronic, and catalytic properties. We present here an experimental approach based on neutron reflectivity (NR) that allows the ...

Interfacing dielectric elastomer actuators with liquids

Herbert Shea, Samuel Rosset, Alexandre Poulin, Luc Maffli

Methods and materials for liquid encapsulation in thin (19 μm) silicone membranes are presented in this work. A set of 12 liquids including solvents, oils, silicone pre-polymers and one ionic liquid are experimentally tested. We show that all selected liqu ...
