Abstract
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 observations demonstrate that
gravity can have a significant effect on cavitation bubbles. An analysis
of the gravity-induced jets uncovers a scaling law between the size of
bubble-induced jets and the non-dimensional parameter grad(p)*R0/p,
where R0 is the maximal bubble radius and p is the driving pressure.
This scaling law applies to any jet formed in any uniform pressure
gradient grad(p).
