摘要：

A relationship between capillary wave amplitude and the diameter of spherical particles ejected in an ultrasonic atomizer is developed. This relationship predicts a threshold amplitude for the generation of the aerosol and is based upon a bifurcation process to reduce surface energy. The most probable size of particles is found to be a diameter of 0.36Ȋ», where Ȋ» is the wavelength of capillary waves for the system. This result is in excellent agreement with the previously reported empirical median particle diameter of 0.34Ȋ». © 1968, Acoustical Society of America. All rights reserved.
