The present study aims to reduce the amount of pesticide that can be released into environment, soil, air, and water by minimizing the type of nozzle and the use of excess pesticides by making use of the Taguchi method. For this purpose, studies were carried out to determine the spray characteristics of the pesticide. The sodium fluorescein was used in the experiments. In this study, the effects of the nozzle-to-surface distance (spray height), spray pressure, nozzle orifice diameter, and nozzle position angle on the droplet diameter and flow characteristics were investigated using the Taguchi method. The mean diameter values were determined first. Then, the volumetric median diameter (VMD) was considered as performance parameter and L9(34) orthogonal sequence was chosen as the experimental plan for four parameters that were determined. Calculating the VMD considered as the performance characteristics, optimum results were obtained using 6 bar spray pressure, 100 mm spray height, 30o nozzle position angle, and 1.10 mm nozzle orifice diameter. The VMD values were calculated using the image processing method and the effects of the parameters on the droplet diameter were interpreted using charts.

Pestisit Uygulamalarında Kullanılan İçi Dolu Konik Hüzmeli Memelerin Püskürtme Karakteristiklerinin Taguchi Metoduyla Optimizasyonu

Öz

Bu çalışmada, Taguchi yöntemi kullanılarak minimum ilaç kalıntısını sağlayan meme tipini ve fazla ilaç kullanımını en aza indirerek çevreye, toprağa, havaya ve suya karışabilecek ilaç miktarının düşürülmesi amaçlanmıştır. Bu amaç doğrultusunda bitkisel ilaçlamada püskürtme özelliklerinin belirlenmesine yönelik deneysel çalışma yapılmıştır. Deneylerde sodyum fluorescein kullanılmıştır. Çalışmada püskürtme uygulamalarını değerlendirmek üzere dikey dizilmiş suya duyarlı kağıtlardan oluşan deney düzeneğinde, meme-yüzey arası mesafe (püskürtme yüksekliği), püskürtme basıncı, meme orifis çapı ve meme konum açısının damlacık çapı ve akım karakteristiklerine etkileri Taguchi yöntemi kullanılarak incelenmiştir. İlk aşamada ortalama çap değerleri belirlenmiştir. Hacimsel medyan çap (HMD) performans karakteristiği olarak dikkate alınmış ve belirlenen dört parametre için L9(34) ortogonal dizisi deney planı olarak seçilmiştir. Performans karakteristiği dikkate alınarak HMD hesaplandığında optimum sonuçlar; 6 bar püskürtme basıncı 100 cm püskürtme yüksekliği, 30o meme konum açısı ve 1.10 mm meme orifis çapında elde edilmiştir. HMD değerleri görüntü işleme yöntemiyle hesaplanmış, parametrelerin damlacık çapı üzerindeki etkileri grafiklerle yorumlanmıştır.
