Abstract
An ultrasonic nozzle configured to form relatively small drops of liquid at relatively high rates. The nozzle includes two horns, at least one of which includes a ceramic material. The nozzle also includes one or more transducers that cause mechanical motion in at least one of the horns. In addition, a method of forming micrometer-scaled drops of liquid at relatively high rates is provided.
Claims20
A nozzle, comprising:
- an atomizing section including a ceramic material;
- and
- an intermediate section configured to promote ultrasonic-frequency mechanical motion in the atomizing section.
A method of atomizing a liquid, the method comprising:
- coating a portion of a ceramic surface with a liquid;
- and
- mechanically moving the surface at an ultrasonic frequency.
A nozzle, comprising:
- means for interfacing with a source of a liquid;
- means for forming drops of the liquid having number median drop sizes of less than approximately 20 microns, wherein the means for forming includes a ceramic material;
- and
- means for promoting ultrasonic-frequency mechanical motion in the atomizing means, wherein the means for promoting is positioned between the means for interfacing and the means for forming.
