Foam Destruction by Ultrasonic Vibrations [PDF]

open access: yesJournal of Colloid and Interface Science, 1993
Ultrasonic (US) vibrations prevent formation of foams and promote their destruction if the vibrating element is placed nearby in the surrounding air. The working distance for rapid foam destruction is 10-15 mm when a sharp vibrating tip is used, but is much larger for a broad tip.
