Revision of the mechanisms behind oil-water (O/W) emulsion preparation by ultrasound and cavitation
Abstract
O/W emulsion preparation by ultrasound is more complex than believed until now. High-speed camera recordings reveal additional intermediate W/O and O/W/O stages. Mechanical effects driving ultrasonic emulsification are discussed. The new ultrasonic emulsification model is proposed.
