ABSTRACT
An atomizer can be an independent device or part of a bigger device such as a diesel injector, furnace burner, spray gun, spray drier, or sprinkle chamber. The energy most commonly used is that of the liquid itself. The pressure drop is converted in an atomizer into kinetic energy, which leads to atomization of the liquid. The name swirl atomizer originates from the swirling of the liquid inside the atomizer. The operation of swirl atomizers is based on the principle that the liquid swirling in the swirl chamber leaves it not as a compact jet but as a conical sheet. Jet disintegration can be speeded up by the development of a flat jet in fan spray atomizers. A jet atomizer produces a jet that disintegrates at some distance from the atomizer. Rotary atomizers are most commonly driven by an electric motor and rotate around their own vertical or horizontal axis.
