Spray Deposit Patterns of an Electrostatic Atomizer

Abstract

The deposit patterns of spray droplets, relying primarily on electrostatic and gravitational forces for transportation and subsequent deposition, were investigated. Deposit distributions of charged sprays were measured in a wind tunnel and on artificial plants. The results indicate electrostatic forces can be used to improve the deposit efficiency of spray droplets but an additional force is required to improve canopy penetration and reduce drift susceptibility of airborne charged droplets.
