Analysis for Different Positions of Nozzle on Air-Assisted Boom Sprayer

Abstract:

Natural wind, relative position between the nozzle and the outlet of the ram in the air-assistant spray have a great influence on performance. Air-assisted boom sprayer model is developed based on CFD. According to the data of the related parameters of the spray machine, variables of 3-D model were defined. With velocity of natural wind and inlet of the ram , the spraying flow keeping constant, the relative position between the nozzle and the outlet being a research variable, this article calculates the drift rate of the droplets respectively, then analyzes the results scientifically and gets the corresponding conclusion. At the same time, in order to confirm the reliability of the simulation results, this paper makes an experiment, which is done in Shandong agricultural university spray performance laboratory. Studies have shown that drift rate is significantly lower when the nozzles located under outlet position than on the downwind or the upwind .
