Apparatus which is selectively operable at low frequencies (less than 5,000 Hz and preferably between about 100 Hz to about 1,000 Hz) breaks up jets of high-viscosity fluid into monodisperse droplets. The apparatus includes a housing having a chamber, a piston disposed in the chamber, a magnetic-coil system operably attached to the housing and to the piston, and an oscillator for driving the magnetic-coil system. The housing and the piston define a reservoir for receiving a supply of high-viscosity fluid which is acted upon by oscillating motion of the piston to impart pressure perturbations on the supply of fluid so that the fluid upon discharge from the reservoir separates and breaks up into a plurality of monodisperse droplets. Also disclosed is a method for optimizing the performance of the apparatus to minimize the power required for droplet formation.

Apparatus for atomizing high-viscosity fluids

A precipitation jet includes a nozzle having an inlet for receiving liquid resin solution, a conical tip, and a plurality of circumferentially spaced apart outlets extending through the nozzle tip for discharging the resin solution. A tubular receiver is disposed coaxially with the nozzle tip and is spaced axially therefrom. The receiver includes a frustoconical impingement surface spaced axially from the nozzle tip to define therewith an annular flow channel having at opposite ends thereof a channel inlet for receiving steam and a channel outlet for discharging an atomized spray of the steam and resin solution for precipitating resin powder from the spray.
