Abstract

Electrostatic (ES) force fields have been employed in the design of Electrostatic swirl nozzle for increasing deposition efficiency, reducing the drift of pesticides. The designed induction charge based electrostatic hand pressure knapsack sprayer offered minimum possible distance between induction electrode and liquid sheet. The experiments were conducted in air atmosphere at ambient conditions (T=20±2 °C, RH= 57±3%) for liquid feed rate 340ml/min at applied hand pressure of 30psi and applied voltage ranging from 0 V to +5 kV. The charging efficiency of 0.37mC/kg at volume median diameter (VMD) of 100 μm has been measured at 3.3 kV. The evaluation was done with an artificial target in laboratory. Uniform deposition in hidden areas of the target was 2.0-2.5 fold increment.
