ULTRASONIC DISSEMINATION OF AEROSOLS

Abstract

An investigation of the generation of aerosol by ultrasonic means was started. Although the work was terminated before it could be completed, the methods and results of this report should be useful in any future study. The theory of a liquid flow over the surface of an oscillating reed was studied to help the understanding of high flow-rate devices. A simple resonance theory has been developed which contrasts with the usual parametric capillary wave theory. An experimental photo-optical technique has been devised and used to give quantitative information on droplet size and velocity distributions. Capillary wave behavior has been examined experimentally and compared with existing theory. A possible explanation of the transition of capillary waves to an aerosol has been suggested. The existence of cavitation during sonic aerosol production from water was verified.
