Micromachined silicon ultrasonic atomizer

1996 IEEE Ultrasonics Symposium. Proceedings, 2002
High 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 ...

Ultrasonic Atomization of Liquids

The Journal of the Acoustical Society of America, 1963
A 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.

A pinhole-plate ultrasonic atomizer

Ultrasonics, 1984
Abstract 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 ...

Ultrasonic atomization: Effect of liquid phase properties

Ultrasonics, 2006
Experiments 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 Liquids

The Journal of the Acoustical Society of America, 1962
An experimental study was made of the mechanism by which the ultrasonic vibration of liquid surfaces causes atomization. At exciting frequencies in the range of 10 to 800 kc, uniform patterns of crossed capillary waves were found on the liquid surface when atomization occurred.

Industrial and medical uses of ultrasonic atomizers

Ultrasonics, 1972
Abstract 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 Atomic Force Microscopy UAFM

2012
A version of scanning probe acoustic technique was developed as ultrasonic atomic force microscopy (UAFM), where higher order mode cantilever vibration is excited at its base (support). It enables precise imaging of both topography and elasticity of stiff samples such as metals and ceramics, without a need for bonding a transducer to the sample.

High volume ultrasonic liquid atomizer

The Journal of the Acoustical Society of America, 1987
An ultrasonic liquid atomizer particularly for high volume flow rates is disclosed. An enlarged tip with a plurality of orifices is provided to increase the flow rate. A gradual transition to the enlarged atomizer tip is provided to enhance performance.
