High-Frequency Ultrasonic Atomization With Pulsed Excitation

Journal of Fluids Engineering, 2003
Ultrasonic atomization is a very convenient method to produce sprays of very small droplets. Resulting droplet size distributions are very narrow and the mean diameter is essentially only controlled by the excitation frequency. Generation of droplets in the micron range requires MHz waves, with voltages around 30 V, which translates into power ...
