The quest for the most spherical bubble: experimental setup and data overview

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

We describe a recently realized experiment producing the most spherical cavitation bubbles today. The bubbles grow inside a liquid from a point plasma generated by a nanosecond laser pulse. Unlike in previous studies, the laser is focussed by a parabolic m ...

Energy partition at the collapse of spherical cavitation bubbles

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

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 ...

Confined shocks inside isolated liquid volumes: A new path of erosion?

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

The unique confinement of shock waves inside isolated liquid volumes amplifies the density of shock–liquid interactions. We investigate this universal principle through an interdisciplinary study of shock-induced cavitation inside liquid volumes, isolated ...

Techniques for generating centimetric drops in microgravity and application to cavitation studies

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

This paper describes the techniques and physical parameters used to produce stable centimetric water drops in microgravity, and to study single cavitation bubbles inside such drops (Parabolic Flight Campaigns, European Space Agency ESA). While the main sci ...

Cavitation Bubble Dynamics inside Liquid Drops in Microgravity

Mohamed Farhat, Nicolas Dorsaz, Claude Nicollier, Danail Obreschkow, Philipp Kobel, Aurèle De Bosset

We report a fundamental study of single cavitation bubbles inside quasi-spherical water drops produced in microgravity (42nd ESA parabolic flight campaign, 8th ESA student parabolic flight campaign). High-speed imaging revealed implications of isolated, fi ...

Interaction of a cavitation bubble with a spherical free surface

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

The dynamic of a cavitation bubble inside a water drop is investigated in microgravity in order to analyze the interaction between the collapsing bubble and a quasispherical free surface. Tests are carried in the frame of the 42nd parabolic flight campaign ...
