Abstract: Fluid dispersal systems and methods of controlling such systems are provided. A method for emitting a fluid from an aerial fluid dispersal system includes receiving data corresponding to an initial aerial distribution profile of fluid emitted by the aerial fluid dispersal system across a distribution width. The fluid is emitted through a plurality of individually controlled nozzle assemblies, and an emission rate of the fluid emitted from a respective nozzle assembly of the plurality of nozzle assemblies is based on an operating parameter of a valve assembly of the respective nozzle assembly. The method also includes determining an effect of the emission rate of each respective nozzle assembly on the initial aerial distribution profile of the fluid across the distribution width. The method also includes controlling the operating parameter of each respective valve assembly to adjust the emission rate of each respective nozzle assembly to generate a compensated distribution profile.

Abstract: Silencing and separation in a cold-air, essential-oil, diffuser apparatus and method pass flow through a channel having comparatively high aspect ratios of length to thickness and width to thickness. Curved, tapered, non-parallel, and quasi random surfaces reduce probability and power of resonant frequencies. Offsetting flow through a channel is followed by impingement against an obstructing surface, redirection elsewhere within a drift (separation) chamber, and exiting through a smaller, and differently oriented exit port. Silencing is improved by changes of cross-sectional area creating high-pass and low pass acoustic filters, changes of direction, and absorption of acoustic energy in fluid-droplet-laden air.
