Abstract
A method for atomizing a liquid (L) in a spraying nozzle (), wherein a gaseous phase (G) and a liquid (L) are fed to a mixing chamber () inside a nozzle (), obtaining an emulsion of the gas in the liquid, the emulsion being under pressure inside the chamber and formed by gas bubbles enveloped by the liquid in a film state. The speed of the gaseous phase at the inlet of the mixing chamber is around the speed of sound or greater. The atomized liquid is obtained by an expansion of the emulsion at the outlet of the chamber. A suitable nozzle () is also disclosed, comprising a mixing chamber () and a distribution device (D) adapted to provide appropriate gas and liquid feed to form an emulsion.
