This study aimed at providing a data-driven understanding of air velocity profiles for four commercial airblast sprayers widely used in the Pacific Northwest (PNW) region of the United States. The Rear’s Powerblast (S1) and Pakblast (S2), Turbomist 30P (S3), and Columbia Accutec (S4) were evaluated using the Smart Spray Analytical System (Bahlol et al., 2020). Air velocity contour profiles and geometrical attributes (symmetry and uniformity) were characterized on two sides as well as at three horizontal distances from the outlet (0.6, 1.5, and 2.1 m) of each sprayer. The air velocity profiles were matched to vertical canopy zones of three typical perennial specialty crops (cherry, apple, and grapevine) to identify their suitability. Air velocity... |
