Abstract
An ultrasound atomization apparatus including an ultrasound transducer, a horn attached to the distal end of the transducer, a chamber within the horn that receives a fluid to be atomized, a radiation surface, and a channel leading from the chamber to the radiation surface. Vibrations produced by the transducer travel down the horn to the radiation surface. The vibrations induce the release of energy into the fluid to be atomized as it travels through the horn's internal chamber and exits the horn at the radiation surface. Controllably increasing the kinetic energy of the fluid, energy emitted into the fluid assists and/or drives fluid atomization. Assisting and/or driving fluid atomization by utilizing vibrations to increase the kinetic energy of the fluid, the ultrasound atomization apparatus can preserve a desired spray pattern when changing environmental conditions would otherwise destroy the spray pattern and/or reduce atomization.
