Uittreksel

The quality of agricultural sprayers is determined by their ability to maintain the balance between on- and off-target deposition. In order to address some orchard spraying issues, the performance of three orchard sprayers (BAB Duoprop, Hardi Condor V and Hardi Tango) are characterized using Computational Fluid Dynamics (CFD). The right sides of the sprayers were modelled at high fan speed settings for airflow. Albuz ATR orange and red nozzles, respectively, for the first two and for the last sprayer were used for spray flow. The CFD models represent controlled trials carried out indoor using artificial pear trees made of wooden stalk and ficus branches. All sprayers showed poor deposition on the top part of the canopy wit the best results for the Duoprop and the worst for the Condor V. Though both sprayers showed high off-target deposition above 2 m, the greatest losses were found for the Condor V. Generally Duoprop sprayer gave the highest leaf deposition and Tango the least lowest. The model proved that the magnitude, pattern and uniformity of the airflow from the sprayers dictates the spray flow and deposition.
