CFD AND TEST OF SINGLE SIDE GANTRY BOOM SPRAYER FOR APPLE ORCHARDS

Aiming at addressing the uneven pesticide distribution when spraying high-spindle apple trees, parameters of a homemade profiling boom sprayer were analysed, and optimal parameter combinations determined. Fluent was used to simulate spray for various values. The goodness fit (R2) with experimentally measured data 0.9270, which verified accuracy numerical simulations. response surface methodology (RSM) method obtain values from simulations, effective collection rate coefficient variation introduced as A prototype manufactured based on determined by RSM analysis, results vertical droplet tests. showed that quality increased 0.7%, 0.9%, 0.3% three best combinations, more uniform, effect better than control can provide guidance design sprayers orchards, combination basis subsequent research precision modelling profile spraying.
