Abstract:
A method of producing concentrically positioned streams, comprising the steps of:(a) forcing a liquid formulation comprising a first liquid through a channel of a first feeding source in a manner which causes a stream of the first liquid to be expelled from a first exit opening at a first velocity; (b) forcing a liquid comprising a second liquid through a second channel concentrically positioned around the first channel in a manner which causes a stream of the second liquid to be expelled from a second exit opening at a velocity which is substantially the same as the first velocity whereby the stream of second liquid is concentrically positioned around the stream of the first liquid; (c) forcing a gas through a pressure chamber in a manner which causes the gas to exit the pressure chamber from an exit orifice positioned downstream of the concentrically positioned streams of the first and second liquids; wherein the density of the liquid formulation is substantially the same as the density of the second liquid, and wherein the gas focuses the concentrically positioned streams to a stable unified jet which flows out of the chamber exit orifice.
