US Patent 7380918 Method and apparatus for forming high-speed liquid

A method and apparatus for forming high-speed water droplets takes advantage on a synergy of features disclosed by the present invention including a low Weber number in a chamber in which a liquid stream breaks up into droplets; a reduced break up distance for forming the water droplets by introducing turbulence into the liquid source, thereby providing a unit or tool that is of practical size; accomplishing the generation of high-speed water droplets without using a complex driver; reducing the liquid's surface tension thereby facilitating the creating of near spherical droplets; and maintaining the droplets in form until they strike the surface of a workpiece.
