  • Spray generators
    Patent number: 4943007
    Abstract: A spray generator for producing a spray of liquid droplets of a narrow size spectrum in which a substantially uniform cyclic disturbance is imposed on fluid energing at a nozzle. Such a disturbance can be produced by a fluidic bistable oscillator or by allowing the fluid to flow across a bluff body in the flow path. An opposed jet arrangement can be located within the vortex chamber of a fluidic diode and the liquid spray produced can meet swirling gas introduced at tangential inlets to the chamber.
