Abstract: A controlled-volume spray deposition system has a fluid feed system including a pair of bi-directional, counter-rotating rollers to dispense fluid as a first surface, the rollers operable to rotate in a first direction to dispense the fluid, a second surface positioned to receive the fluid when the rollers rotate in the first direction, and the rollers operable to rotate in a second direction to retract the fluid to cause the fluid to stretch and form a filament until it breaks to form a spray. A method of generating a controlled-volume spray includes feeding fluid between two counter-rotating rollers as a first surface as they rotate in a first direction until the fluid contacts a second surface, reversing the counter-rotating rollers such that they pull the fluid to form a fluid filament, and causing the filament to break into a spray.

Abstract: Aerosols can be created by filament stretching and breaking of Newtonian and non-Newtonian fluids by applying a strain to and stretching the fluid. The fluid is stretched along a strain pathway and forms a fluid filament between diverging surfaces. The stretched fluid filament breaks into droplets that can be harvested to form a mist or aerosol. The aerosol creation systems can include one or more pairs of counter-rotating rollers that are positioned adjacent to each other that stretch the fluid or a pair of pistons that move toward and away from each other to stretch the fluid. Some aerosol creation systems can include multiple pairs of counter-rotating rollers that are positioned in a circular, oval, or linear pattern. The aerosol creation system with multiple pairs of counter-rotating rollers can generate mist is one or more directions and can be positioned between two concentric rings or linearly, among other configurations.

Abstract: Aerosols can be created by filament stretching and breaking of Newtonian and non-Newtonian fluids by applying a strain to and stretching the fluid. The fluid is stretched along a strain pathway and forms a fluid filament. The fluid filament is caused to break into droplets that can be harvested to form a mist or aerosol. Such a system for aerosol creation can include a pair of counter-rotating rollers that are positioned adjacent to each other that stretch the fluid or a pair of pistons that move toward and away from each other to stretch the fluid.
