Spray nozzle characterization using a backlighted high speed imaging technique

Abstract : Agricultural pesticide sprays are applied with different types of spray nozzles each with its own spray characteristics. The objective of this study was to measure the macro-spray characteristics (spray angle, liquid sheet length, spray shape) from different types of hydraulic spray nozzles using a developed backlighted image acquisition system and image processing technique. Tests included five different nozzles (Albuz ATR orange and red, TeeJet XR 110 01, XR 110 04 and Al 110 04). The results were compared and related well with the results from existing measuring techniques like a flow rate test bench, a spray distribution bench (horizontal patternator) and a Phase Doppler Particle Analyzer (PDPA) laser.
