Increasing spray deposition while reducing inadvertent off-target movement is critical with agricultural sprays for field protection of crops. Pulsed flow can increase droplet velocity and energy while maintaining desired droplet size spectra from simple-or ice atomizers. Droplet size spectra and velocities were measured using a phase Doppler,laser system for hydraulic atomizing nozzles producing liquid flow of 1.1 liters/min while pressurized at 50-670 kPa. Typical spray cloud volume median diameters ranged from 210 to 337 mum. Droplet velocities in the droplet diameter range of 150 to 400 pm were increased by 3- to 4-fold, corresponding to a 9- to 16-Jold increase in kinetic energy of the spray droplets in that size range. The cumulative momentum and kinetic energy of the entire spray cloud were in creased by 2-fold and 4.4-fold, respectively. The results confirmed that droplet size spectra could be maintained for adequate target coverage while droplet velocities could be increased to reduce droplet flight times and provide greater kinetic energy for deposition.
