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 ...

Feasibilities of foam-forming bacteria disintegration by ultrasonic atomization [PDF]
EPJ Web of Conferences, 2022 This article presents the feasibilities of bacterial disintegration using ultrasonic atomization. Ultrasound creates acoustic cavitation, which by its effects represents a high gradient of pressure in the form of a shock wave and a local force effect. In

Influence of liquid properties on ultrasonic atomization [PDF]
Proceedings ILASS–Europe 2017. 28th Conference on Liquid Atomization and Spray Systems, 2017 Ultrasonic atomization is very convenient because it can generate droplets with diameters of a few microns andwith very narrow size distribution. Besides, opposite to twin fluid nozzles, in ultrasonic atomization, dropletgeneration and transport are decoupled processes.

Dynamics of ultrasonic atomization of droplets
Experimental Thermal and Fluid Science, 2018 Abstract We investigate the atomization behavior of a droplet subjected to ultrasonic substrate vibration experimentally. High-speed imaging is employed to quantify the average atomization lifetime of the droplet as a function of initial droplet size and different fluid properties.

Ultrasonics Sonochemistry, 2017 Ultrasonic atomization is used to produce fine liquid mists with diameter ranges below 100nm. We investigated the effect of the frequency on the size distribution of ultrasonic mist. A bimodal distribution was obtained for the mist generated by ultrasonic atomization with a wide-range particle spectrometer.
