Abstract

The volumetric deposition pattern is an important parameter for spray nozzle selection for each pesticide application. Thus, the objective of this study was to evaluate the volumetric distribution uniformity of air induction twin flat spray nozzles, with different nominal flows, under different work pressures and heights on the test table (patternator). It was evaluated the deposition pattern of each nozzle individually, in a test table, and then the coefficient of variation of the nozzle distribution influenced by the relationship between nozzles spacing and height was simulated. The uniformity of volumetric distribution was influenced by nominal flow, liquid pressure, and working height. The nozzles, in a general way, presented good distribution uniformity, mainly those with larger nominal flow. The accomplished simulations allowed the selection of the best operational conditions for each nozzle.

KEY-WORDS: Application technology; spray nozzle; distribution patterns.
