Research on Droplets Deposition Characteristics of Anti-Drift Spray Device with Multi-Airflow Synergy Based on CFD Simulation

Applied Sciences, 2022
With the increase in orchard areas and the transfer of rural labor, various air-assisted sprayers have been widely used in China. However, the problem of off-target drift still exists, which has caused pesticide waste and environmental pollution.

Performance of selected agricultural spray nozzles using particle image velocimetry [PDF]

, 2015
The aim of the present study was to investigate the influence of nozzle configurations on spray drift and explain the influences using several atomization characteristics (length of spray sheet, spray angle, velocity distribution of flow field ...

Use of rotary atomiser to optimize retention on barley leaves while reducing driftable droplets [PDF]

, 2014
Controlled Droplet Application using rotary atomiser is based on an improved control of droplet size and trajectory comparatively to hydraulic nozzles. On the basis of literature, it was stated that the use of 60° forward angled spray combined with the ...

Impacts of Climate Change on indirect human exposure to pathogens and chemicals from agriculture [PDF]

, 2008
Objective: Climate change is likely to affect the nature of pathogens and chemicals in the environment and their fate and transport. Future risks of pathogens and chemicals could therefore be very different from those of today.

The Influence of Lateral Wind Velocity on Spray Drift Dynamics of Liquid Droplets Sprayed by Agricultural Robot

Applied Sciences
During the spraying operation, it is important to consider the environmental conditions, particularly the wind velocity. Droplets carried by the wind out of the spray zone may be carried onto nearby plants, soil, water bodies, residential areas, etc ...
