Abstract
A system and method for determining the atomization characteristics of fluids is disclosed. In one embodiment, a fluid is emitted through a nozzle at controlled conditions. Vibrations occurring within the nozzle are sensed while the fluid is being emitted. An atomization characteristic of the fluid is predicted using the sensed vibrations. In one embodiment, the sensed vibrations are converted into a spectral density that is used to calculate a vibration power spectrum. In one embodiment, the atomization characteristic is the droplet size of the fluid with respect to the controlled conditions, and the droplet size is predicted based on a relationship between a descriptive attribute of the fluid and the vibration power spectrum of the fluid. In one embodiment, the descriptive attribute is the volume median diameter of the fluid.
