DROPLET GENERATOR AND METHOD

摘要

A droplet generator and method for dispersing a liquid feed stock into uniform spherical droplets. The apparatus includes means for providing a jetstream of the liquid feed stock, means for generating uniformly periodic varicose instabilities in the jetstream, and means for providing a concurrent, coaxial flow of gas surrounding the jetstream in order to enhance the varicose instabilities in order to cause the uniform dispersion of the jetstream into uniform spherical droplets. It is desirable that the varicose instabilities have a wavelength of at least pi times the unperturbed diameter of the jetstream.
