Various methods can be used to numerically simulate the aerodynamic separation of fine-grained bulk material, including discrete element methods, finite element methods, and bounded domain methods. In all these methods, these equations are solved numerically, and the results are used to determine the trajectories and velocities of air and particles. The Discrete Element Method (DEM), on the basis of which the study will be conducted, is designed for modeling the granular flow of materials. The purpose of the research is to simulate the movement of fine-grained loose material under the influence of air flow and calculate the parameters of its aerodynamic separation in the Simcenter STAR-CCM+ software package. The following were selected as physical models: gas, two-dimensional, separated flow, gradients, ideal gas, isothermal fluid energy equation, unsteady implicit, turbulent, Reynolds averaging of the Navier-Stokes equation, K-Epsilon turbulence model, admissible two-layer K-Epsilon, wall distance, double layer for any y+, gravity, Lagrangian multiphase, DEM discrete element model, multiphase interaction. As a result of the numerical simulation of the movement of fine-grained loose material under the influence of the air flow in the Simcenter STAR-CCM+ software package, the distribution of their components in the area of the separator was constructed. The following parameters were adopted as research factors: the diameter of the particles of the liquid fraction and impurities d, the particle supply speed f, the air flow speed v. Based on the results of the processing of the obtained data set in the Wolfram Cloud software package, the patterns of changes in the position of the intersection line of the distribution of two fractions (distance x) and the content of impurities δ in the liquid zone of separation from research factors were established. The presented detailed method of numerical modeling can be used to study other methods of separation of fine-grained loose materials.

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.
