Capillary waves control the ejection of bubble bursting jets

WebAt the same time, two opposing jets are produced pointing to the opposite plate. The jet passes through the sub-bubbles and vortexes form in the center of the bubbles. The vortex attracts the edges of bubbles converge into the central, forming distinctly bevel. Bubble jets pass through the entire bubble, forming ring bubbles and eventually ... WebThe movement of the jet gradually tears the bubble into several annular bubbles. The collapsed bubble is different from the closed cavity in that there is an upward jet at the bottom when the closed cavity collapses, and no apparent bottom jet is produced at the bottom of the bubble when the bubble collapses after the bubble is reclosed. list of christian behaviors
