Shape Oscillations of a Bubble or Drop Attached to a Capillary Tip

Popis výsledku v původním jazyce

The oscillation dynamics of bubbles and drops that are attached to the tip of a capillary are experimentally investigated to test the applicability of simplified linear analyses to real-world situations. The experiments are performed with 0.7?2.6 mm airbubbles in pure water and with 0.7?1.3 mm drops of pure water. The bubbles or drops are excited by the vertical motion of the capillary. The shape oscillations are recorded by a high-speed camera and are processed to determine the oscillation eigenmodes(their frequencies, shapes, and damping rates). If the bubbles or drops are sufficiently small , the measured characteristics of the eigenmodes will correspond to the analyses. If the bubble or drop size is sufficiently large to form a neck, the eigenmode frequency decreases and the shape oscillations will correspond to those of a free bubble. The reduction in eigenmode frequency is correlated with the ratio of the actual volume of the bubble to the detachment volume of the bubble.
