Abstract
ABSTRACT Amathematical (computer) model was developed for describing the effect of external air flow on the air velocity field induced by an orchard air sprayer jet. Four 1/12-scale physical models of an orchard sprayer were used to measure the effect of wind and/or travel speed, simulated by a wind tunnel, on air sprayer jets. Beyond 10 cm from the outlet, computer-predicted, jet centerline velocities were within 1-3 m/s of measured velocities. For crossflow velocities of 6.7 m/s, the computer model accurately predicted jet deflection. However, at crossflow velocities of 3 and 4 m/s measured jet deflection was somewhat greater than predicted deflection, especially for narrow outlet widths. Crossflows from 45 deg with respect to direction of the jet at the outlet deflected jets more than crossflows from 90 deg. For jets with equal power at the outlet, jets with narrow outlet width were deflected more than jets with wide outlet width
