Abstract
A method of creating aerosols includes drawing a fluid from a fluid source through a first nip, the first nip defined between a first roller and an inner surface of a ring, the first nip having an upstream side and a downstream side, drawing the fluid from the fluid source through a second nip, the second nip defined between a second roller and the inner surface of the ring, the second roller positioned adjacent to and spaced apart from the first roller in a circular configuration, the second nip having an upstream side and a downstream side, stretching the fluid between diverging surfaces of the first roller and the inner surface of the ring on the downstream side of the first nip to form a first fluid filament, stretching the fluid between diverging surface of the second roller and the inner surface of the ring on the downstream side of the second nip to form a second fluid filament, causing the first fluid filament to break into a plurality of first droplets, and causing the second fluid filament to break into a plurality of second droplets.
