Survey of the Literature: Controlled Generation of Liquid Droplets

Abstract

Techniques utilized in generating large drops from visco-elastic liquids, which are also referred to as non-Newtonian liquids, are surveyed, reviewed and evaluated. The minimum droplet size of interest was 0.2 mm (200 micrometers). Drop generation techniques considered include the capillary dropper, liquid jets, atomization, the spinning disc, vaporization-condensation, impulse generation, and other techniques. Of these, only three generator configurations were found to meet experimental requirements. These included a drop impulse/ejection system, a capillary device utilizing immiscible liquids, and a microfilm technique whereby presized drops are released into free fall by the sudden removal of the supporting microfilm utilizing a liquid solvent spray technique. Keywords: Evaporation.
