Effect of soluble surfactant on bubble persistence and bubble-produced aerosol particles

The effect of soluble surfactant on the persistence of salt-water bubbles and their ability to produce aerosol particles upon bursting was investigated. Ensembles of individual, millimetric bubbles were produced in NaCl solutions of varying surfactant conc ...

Evidence for hydrogen generation in laser- or spark-induced cavitation bubbles

Mohamed Farhat, Marc Tinguely

The growing use of focused lasers or electric sparks to generate cavitation bubbles raises concerns about the possible alteration of gas content during the initiation process and its effect on bubble dynamics. We provide experimental evidence that hydrogen ...

Light induced fluidic waveguide coupling

Christophe Moser, Eric Tremblay, Volker Günter Zagolla

We report on the development of an opto-fluidic waveguide coupling mechanism for planar solar concentration. This mechanism is self-adaptive and light-responsive to efficiently maintain waveguide coupling and concentration independent of incoming light's d ...

Rational asset pricing bubbles and portfolio constraints

Julien Hugonnier

This article shows that portfolio constraints can give rise to rational asset pricing bubbles in equilibrium even if there are unconstrained agents in the economy who can benefit from the induced limited arbitrage opportunities. Furthermore, it is shown th ...

Interface-induced recirculation within a stationary microfluidic drop

François Gallaire

We study the flow within a stationary drop in a Hele-Shaw cell. The experiments are performed in a microfluidic channel, whose surface is patterned with a single hole that serves to anchor the drop while the outer fluid continues to flow. The recirculation ...

Dynamic Pressures around a Confined Block Impacted by Plunging Aerated High-Velocity Jets

Anton Schleiss, Erik Bollaert, Rafael Xavier Meriade Duarte

The impingement of high-velocity water jets on unlined plunge pools causes scour on the rock foundations. The scour process is the result of complex physical phenomena that happen consecutively. Turbulence and dynamic pressures play a major role, especiall ...

Energy partition at the collapse of spherical cavitation bubbles

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Aurèle De Bosset, Marc Tinguely

Spherically collapsing cavitation bubbles produce a shock wave followed by a rebound bubble. Here we present a systematic investigation of the energy partition between the rebound and the shock. Highly spherical cavitation bubbles are produced in micrograv ...

Femtosecond-laser generation of self-organized bubble patterns in fused silica

Yves Bellouard, Max-Olivier Hongler

By continuously scanning a femtosecond laser beam across a fused silica specimen, we demonstrate the formation of self-organized bubbles buried in the material. Rather than using high intensity pulses and high numerical aperture to induce explosions in the ...

Universal Scaling Law for Jets of Collapsing Bubbles

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Aurèle De Bosset, Marc Tinguely

Cavitation bubbles collapsing and rebounding in a pressure gradient del p form a "microjet" enveloped by a "vapor jet." This Letter presents unprecedented observations of the vapor jets formed in a uniform gravity-induced del p, modulated aboard parabolic ...
