Characteristics on the Spatial Distribution of Droplet Size and Velocity with Difference Adjuvant in Nozzle Spraying

The spatial distribution of droplet size and velocity affects the deposition on target. In order to investigate influence different adjuvant pressures in atomization area nozzles, air induction flat fan nozzle IDK120-03, multi-range LU120-03 anti-drift AD120-03 were selected. Phase Doppler Interferometer (PDI) was used analyze compare three nozzles when four typical Maisi, Maidao, Adsee AB-600 Surun sprayed at pressures. results show that volume median diameter has no obvious change along vertical direction center increases with distance horizontal direction, decreases increasing pressure same position, all (about 12%, 10% 9% for AB-600, respectively), IDK120-03 is largest smallest position. For distribution, decrease respectively, compared water, increased by about 13%, 9%, 8%, 4% Surun, AD IDK experiment can provide a basis selection adjuvants pesticide application, data base studying droplets
