ABSTRACT

The quality of agrochemical spraying depends on speed of the sprayer and cross wind. Dynamic spray mechanism was designed and installed in the wind tunnel for simulating the effect of speed of the sprayer and cross wind combinations on droplet spectra classifications (DSC). It is able to generate two dimensional spraying (2D) at uniform sprayer speeds under wind tunnel conditions. Droplet spectra classifications were studied using water sensitive papers (WSPs). The effect of cross wind and sprayer speed on dynamic spray was analysed and compared with reference spraying. The result of the tests showed that there were differences in the DSC when speed of the sprayer and wind speed increased. This spray mechanism was suitable for the assessment of the dynamic spray.
