ABSTRACT:
The spraying nozzle of this invention establishes supersonic gas jets directed towards an edge on two liquid flow surfaces formed by that edge. High frequency aerodynamic oscillations are generated in front of the edge. Liquid is supplied to the liquid flow surfaces. The gas flow spreads liquid on a liquid flow surface into a thin film which flows along the liquid flow surface towards the edge. The thin film flow becomes thinner, separates from the edge, and is sprayed as liquid droplets. The liquid droplets are sucked into the gas jet convergence point where they are further fragmented into extremely fine particles by shock waves of the gas jets. The ultra-fine particles are rapidly swept away from the edge by the gas flow.
