Abstract

Bubble and drop breakage in turbulent liquid flow in a pipeline was observed to determine the mechanism of breakup. Bubble breakage sequences from high-speed movie film were examined to determine a breakage time, the number of bubbles formed, and bubble sizes. Bubble breakage was observed only at dimensionless radii greater than 0.5 and only two bubbles were formed. The bubble breakage is caused by a surface disturbance which eventually deforms the bubble into a dumbbell shape. The sizes of the resulting two bubbles have a higher probability of being of unequal volume than equal volume. Preliminary results from drop breakage experiments indicate that bubbles and drops have similar breakage mechanisms and that the time to break ranges from 0.01 to 0.1 s.
