9 results about "Ultrasonic nozzle" patented technology

Ultrasonic nozzles are a type of spray nozzle that uses high frequency vibration produced by piezoelectric transducers acting upon the nozzle tip that will create capillary waves in a liquid film. Once the amplitude of the capillary waves reaches a critical height (due to the power level supplied by the generator), they become too tall to support themselves and tiny droplets fall off the tip of each wave resulting in atomization.
