Shock waves from non-spherical cavitation bubbles
Outi Supponen, Danail Obreschkow, Philippe Kobel +3
We present detailed observations of the shock waves emitted at the collapse of single cavitation bubbles using simultaneous time-resolved shadowgraphy and hydrophone pressure measu…
Scaling laws for jets of single cavitation bubbles
Outi Supponen, Danail Obreschkow, Marc Tinguely +3
Fast liquid jets, called micro-jets, are produced within cavitation bubbles experiencing an aspherical collapse. Here we review micro-jets of different origins, scales and appearan…
The Quest for the Most Spherical Bubble
Danail Obreschkow, Marc Tinguely, Nicolas Dorsaz +3
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 las…
Bubble-Jets in Gravitational Fields (APS DFD Video V060)
Danail Obreschkow, Marc Tinguely, Nicolas Dorsaz +3
We show visualizations of the gravity-induced jets formed by spherical bubbles collapsing in liquids subjected to normal gravity, micro-gravity, and hyper-gravity. These observatio…
A Universal Scaling Law for Jets of Collapsing Bubbles
Danail Obreschkow, Marc Tinguely, Nicolas Dorsaz +3
Cavitation bubbles collapsing and rebounding in a pressure gradient grad(p) form a "micro-jet" enveloped by a "vapor jet". This letter presents unprecedented observations of the va…
Confined Shocks inside Isolated Liquid Volumes -- A New Path of Erosion?
Danail Obreschkow, Nicolas Dorsaz, Philippe Kobel +4
The unique confinement of shock waves inside isolated liquid volumes amplifies the density of shock-liquid interactions. We investigate this universal principle through an interdis…
