✦ Synopsis

larger than a critical diameter move along an oscillatory This paper presents the results of numerical simulations for path. The oscillation may be either a zigzag or a helix. Saffbubble motion in water. The motion is axisymmetric and steady man found that, in filtered water, bubbles in the range 1.4 in the bubble's frame of reference. It is assumed that the liquid is mm õ d e õ 4.6 mm oscillated. He found that bubbles zigquiescent except for the motion created by the bubble. The bubble zagged near the threshold of oscillatory motion, but that Reynolds numbers range up to roughly 600. The results for clean larger bubbles spiraled. In tap water, he found similar behavinterfaces are compared with Duineveld's experiments. The insoluior except that oscillatory motion began at d e Å 1.6 mm. ble surfactant model is used to model the behavior of bubbles in Hartunian and Sears found different results for the onset contaminated water. Calculations of wake volumes are presented.
