Turbulent fluid mixing is an important aspect of many industrial and technological processes where efficient mixing of various components is of paramount importance to achieve the desired results. Optimal mixing can improve product quality, ensure the unity of complex reactions, and reduce process lead times. In this regard, the study and understanding of the influence of the geometry of the mixer on the characteristics of the turbulent flow becomes an urgent task of scientific research.
The relevance of the study is explained by the wide application of mixers in industrial and technological processes, where the efficiency of mixing is crucial for achieving optimal results.
The work used methods of experimental and numerical modeling of turbulent flow in various geometric configurations of blade mixers. Indicators such as turbulence intensity, pressure gradient, and fluid mixing ratio were used to quantify the turbulent characteristics.
The obtained results demonstrate that the geometric configuration of the blade mixer has a significant effect on the formation of the turbulent flow. Some geometric parameters of the mixer can contribute to increasing the intensity of liquid mixing, while others can reduce its efficiency.
Scientific results can be useful for designing optimal paddle mixers for specific industrial tasks that require intensive liquid mixing. The use of optimized mixers can help increase process productivity, save energy resources, and improve product quality.

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.
