Observation and Analysis of Surface Acoustic Wave Induced Atomization [PDF]

, 2007
The ability to excite instabilities in free fluid surfaces via acoustic excitation is well known, even to the point of atomization. Surprisingly, atomization phenomena exist at frequencies up to 1 GHz, because peak piezoelectrically-driven vibration ...

The Influence of the surface hardness on the atomization performance of ultrasonic atomizer

Journal of Physics: Conference Series
Abstract In the actual production of ultrasonic atomization, to cater to the consumers’ preference for the appearance of the products, the surface of the ultrasonic atomizer needs to be treated with different machining processes, which tend to affect the surface hardness of the atomizer, and affect the atomization performance of the ...
