Abstract

High-speed video is used to analyze the pinch-off of xenon in water. By varying the pressure in the xenon from 0.05 to 68 atm, the mass density ratio D=ρint/ρext of the interior gaseous xenon ρint to the exterior liquid water ρext can be varied by over 3 orders of magnitude. Both the shape of the pinch region and the power law that governs the collapse of the minimum neck radius are distinctly different for the low D (bubblelike) and high D (dropletlike) cases. We show that there is a rather abrupt transition between these types of behavior near D0.25.
