Physical Features of Liquid Atomization when Using Different Methods of Spraying

An experimental study of the peculiarities of atomization of liquids with different physical properties has been carried out. We used hydraulic, pneumatic, and centrifugal-pneumatic methods. The experiments allowed us to justify the assumption of a vortex mechanism of decomposition of liquid films into droplets due to loss of their own stability. It has been shown that, under hydrodynamic and centrifugal-pneumatic spraying, the major influence on the dispersity of aerosols is played by viscosity and surface tension, respectively. In pneumatic spraying, dispersity is mainly determined by the flow of air.
