The spraying process simulation of the low-volume sprayer working body

The article presents the developed mathematical models that describe process of spraying working body a low-volume sprayer. Theoretical studies show with an increase in supply fluid to atomizing disc, rotational speed pneumatic disc atomizer decreases, and order ensure effect air flow on droplet formation process, radius should be larger than base cone-shaped fairing, but less its maximum critical value for obtaining monodisperse spray main diameter d = 80 … 120 μm, at axial velocity fan installation U 40 60 m/s, parameters disk sprayer propeller are linked together when following values: r 65 85 mm, number radial channels nр 2 6 pcs, width channel bр 3 4 obtain high-quality air-droplet flow, initial drops discharged from periphery must and, same time, is recommended used range ω 60… 200 s-1.
