Abstract

Namen diplomske naloge je ovrednotiti aerodinamske lastnosti sadjarskega pršilnika na izstopu iz aksialnega ventilatorja. Izdelana je bila merilna proga, s katero smo premikali krilni anemometer in petluknjično Pitotovo cev po prostoru. Z merilnima zaznavaloma smo merili velikost in smer vektorja hitrosti zračnega toka pri različnih obratovalnih pogojih in oddaljenostih od ustja ohišja pršilnika. Na podlagi rezultatov meritev so analizirani geometrijski vplivi ohišja pršilnika na smer in velikost vektorja hitrosti zračnega toka na izstopu iz pršilnika. Na podlagi teh vplivov na zračni tok je nato podan predlog aerodinamske optimizacije pršilnika, s katero bi zmanjšali izgube fitofarmacevsih sredstev v okolico med obratovanjem pršilnika.

Secondary title:	Measurement of aerodynamic properties of an orchard sprayer
Secondary abstract:	The purpose of the thesis is to evaluate aerodynamic properties of an orchard sprayer at the exit from the axial fan. A measuring line was created, to move 3-Dimensional Pitot probe and the vane anemometer around the space in front of the orchard sprayer. With the measuring equipment, the size and the direction of the velocity vector of the airflow was measured, at different operating conditions and distances from the orchard sprayer housing. Based on the measuring results, the mechanical and geometric effects of the sprayer housing on the direction and size of the air flow velocity vectors are shown, at the exit from the orchard sprayer housing. On the basis of these effects on the air flow, a mechanical optimization is proposed, which would reduce pesticide loss into enviroment, while the sprayer is operating.
