Path instability and wake of a rising bubble

Résumé

The dynamics of millimeter sized air bubbles rising through still water are investigated using precise ultrasound velocity measurements combined with high speed video. From measurements we deduce the forces acting on the bubble and we tie the dynamics of the bubble's wake to observed oscillatory instabilities of the bubble's path: planar zigzag and spiraling motion.
