Abstract: The present invention comprises a nozzle type atomizer with two or more aligned “horn” stages. The definition of a “horn” stage is well known in the prior art as an effectively half wavelength length and a tapering shape with a central conduit. The present invention uses two to five, or more, horn stages integrally attached end to end. The dramatic improvement in amplitude of the vibration at the tip of the nozzle is without precedence in the prior art. The present invention makes application of transducer vibration at greater than 200 kHz possible. The present invention reduces the required applied energy for generating the necessary amplitude at the tip by the discovery of amplitude multiplication with two or more horn stages.

Abstract: The present invention is a dramatic enhancement of the two-fluid atomization art through the discovery of a method of causing resonance between capillary waves in the ultrasound range in a flowing liquid stream and the waves created at the surface of that stream of liquid by an impinging gas stream. In the present invention, the surface of a stream of liquid issuing from the outlet or nozzle of an ultrasonic atomizer is impinged upon by a stream of gas. That impinging stream of gas then develops, at the surface of the liquid stream already sustaining its own wave motion, a flow of gas substantially parallel to the flow of the liquid stream that moves faster than that surface of the liquid stream. The flow of the gas at the surface of the liquid stream moves sufficiently faster than the surface of the liquid stream to generate waves at the surface of the liquid stream.
