Abstract

The article presents the results of experimental studies to determine the dependence of the rotational speed of a pneumatic disc sprayer with coaxial air flow on the flow rate of the working fluid. To refine the parameters of the working body, studies were carried out within the liquid flow rate q, corresponding to the first and second spraying modes, at different rotation speeds ω, the working body's radius r, and the number of radial channels np. At the same time, the mass of the rotating part of the pneumatic disk atomizer was determined. The quality of dispersion of the working fluid obtained experimentally by a multi-disk atomizer in a film version driven by an air flow corresponds to a low-volume liquid atomization mode.
