Abstract:
A method of manufacturing a gasdrop comprising the steps of:(i) beginning injection of a gas into a chamber, wherein said beginning injection of said gas goes into a predetermined substantially enclosed space having an outlet and said gas injection is within a predetermined range of input flow velocities, and within a predetermined range of volumetric input flow rates;(ii) beginning injection of a liquid into said chamber, wherein said liquid injection is within a predetermined range of input flow speeds, and within a predetermined range of volumetric input flow rates, and both said injection occurring at a predetermined location, and further wherein said liquid injection does not begin prior to said gas injection and concurrent with said injections;(a) manufacturing a stream of contiguous bubbles within said chamber, wherein said stream exits via said outlet;(b) inducing an accumulation of said bubbles, wherein said accumulation is contiguous with said outlet; and(c) inducing detachment of said accumulation wherein, said inducement consists essentially of gravitational force.
