Abstract
Rotary atomizers and hydraulic nozzles used in forestry spraying were extensively tested with laser light scattering, laser light imaging, and photographic methods in a specially designed wind tunnel. Data on droplet size distribution and cumulative volume fraction versus droplet size are given. Correlations for reduced volume median diameter (Dv,0.5/d0) and reduced span ((Dv.0.9 – Dv.0.1)/d0) presented. Accuracy of prediction is of the order of 20% for hydraulic nozzle volume median diameter. Accuracy of prediction for high‐speed rotating wire mesh atomizers is of the order of 35% for the volume median diameter. When these accuracies are inadequate, a specific test of the device in question is recommended.Keywords
