Abstract: A fluid dispersion system and method used for spraying large areas with near-monodispersed, aerosolized fluid droplets. More specifically, the system creates and distributes a cloud of near-monodispersed droplets of fluid by pumping pressurized air and fluid through fluid dispersion machinery and into, and out of, a fluid dispersion nozzle. The fluid dispersion machinery is a combustion engine-driven air compressor system that includes an engine, radiator, fuel tank, fluid tank, fluid piping system, fluid pump, air compressor, air compression intake, one or more fluid dispersal nozzles, air ducting, clutch, and control system. The method of fluid dispersion is implemented at night during a nighttime air inversion when there is a temperature difference between the temperature of air at the top of an object and the temperature of air near the ground surface.

Abstract: A fluid dispersion nozzle and system for spraying large areas with near-monodispersed, aerosolized fluid droplets. More specifically, the fluid dispersion nozzle receives pressurized and fluid from fluid dispersion machinery, aerosolizes the fluid into near-monodispersed droplets, and distributes the aerosolized, near-monodispersed droplets evenly over long distances. The nozzle is an adjustable, dual-contour, supersonic nozzle that includes a main adjustable contour, an auxiliary contour, an axial fluid injector, a resonator, and a plunger.
