This scientific paper presents a comprehensive experimental study on the formation of the spray plume and the distribution of the working fluid by centrifugal nozzles under stationary laboratory bench conditions. The relevance of this study is driven by the strict requirements of modern agricultural production to increase the efficiency of plant protection product application while simultaneously minimizing environmental impact. Traditional field tests are often complicated by a number of uncontrolled meteorological factors (wind speed and direction, fluctuations in air temperature and humidity), which significantly reduces the reliability of determining the true performance characteristics of individual nozzles. To solve this problem, the authors applied a laboratory testing methodology using a specialized hydraulic bench manufactured in accordance with current standards, which made it possible to isolate and evaluate the influence of key technological parameters with high precision.
The object of the study is the processes of hydraulic liquid spraying by AM.03.SB and Ej.03 centrifugal nozzles. The subject of the study is defined as the regularities of changes in the coefficient of variation of the transverse distribution of the working fluid depending on the pressure in the pressure manifold and the height of the sprayer boom. During the experimental studies, the working pressure in the hydraulic system ranged from 0.1 to 0.3 MPa with a step of 0.1 MPa, and the boom installation height above the receiving surface varied from 0.30 to 0.50 m with a step of 0.05 m. The obtained arrays of experimental data were processed in the Wolfram Cloud environment, which made it possible to build adequate full second-order polynomial models. These models describe the nonlinear influence of the studied factors on the unevenness index (coefficient of variation) of fluid distribution across the working width.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
