Ultrasonic atomization: Effect of liquid phase properties
Ultrasonics, 2006Experiments have been conducted to understand the mechanism by which the ultrasonic vibration at the gas liquid interface causes the atomization of liquid. For this purpose, aqueous solutions having different viscosities and liquids showing Newtonian (aqueous solution of glycerin) and non-Newtonian behavior (aqueous solution of sodium salt of carboxy ...

Ultrasonic atomization of distilled water
The Journal of the Acoustical Society of America, 2018Experimental data on ultrasonic atomization of distilled water in a frequency range from 5 to 50 kHz are presented. A good agreement was found with the predictions of Rajan and Pandit [Ultrasonics 39, 235–255 (2001)] for the atomized primary drop size as a function of frequency.

Ultrasonic Atomization Studies
The Journal of the Acoustical Society of America, 1966Atomization of selected fluids has been observed to occur in a capillary at various resonance heights of the standing ultrasonic wave in the fluid. The length of fogging has been observed to be a function of the voltage applied to the transducer producing the ultrasonic wave in the fluid.

Industrial and medical uses of ultrasonic atomizers
Ultrasonics, 1972Abstract The methods and uses of this form of atomization are surveyed. The applications range from ordinary liquids to molten metals, from throughputs of fractional gallons per hour to more than 100 Imperial gallons per hour (100 gal h −1 ) or 140 grammes per second (140 g s −1 ), and the resulting drop sizes vary from just above 1 μm to 180 μm, all

Ultrasonic Atomization of Liquids
The Journal of the Acoustical Society of America, 1963A theory of ultrasonic atomization of liquid films is presented. It is assumed that exponential growth of surface disturbances ultimately results in the formation of liquid drops, the diameters of which are proportional to the wavelength of the most rapidly growing initial disturbance.

Micromachined silicon ultrasonic atomizer
1996 IEEE Ultrasonics Symposium. Proceedings, 2002High amplitude ultrasound, generated by a micromachined silicon resonant transducer, was used to atomize and pump liquids. The needle-shaped device made by bonding two silicon horns, is driven by lead-zirconate-titanate (PZT) piezoelectric plates. Water was atomized continuously at feed rates of 2.4 ml/min into a mist with mean drop size of 25 /spl mu ...

Air-assisted ultrasonic atomization
1996 IEEE Ultrasonics Symposium. Proceedings, 2002We have established a correlation between the drop diameter with peak volume-percent of the drop-size distribution obtained in ultrasonic atomization and the wavelength of the capillary waves determined by the ultrasonic frequency in accordance with the Kelvin equation.

A pinhole-plate ultrasonic atomizer
Ultrasonics, 1984Abstract A new pinhole-plate ultrasonic atomizer has been proposed and developed. A pinhole-plate having one or more pinholes is joined to a cavity filled with liquid and is vibrated by a circular ring piezoelectric element bonded onto it. The vibrating plate generates ultrasonic waves only in the vicinity of the pinholes to jet and atomize the ...
