The paper presents the results related to the simulation of dust-separating tangential cyclones: single cyclones of various geometries, and an axial multi-cyclone with fixed geometries and components. Its goal was to apply low-cost analyses for cyclones in industrial realization. Therefore, the presented research was applied with simulation methodology as a problem of Computational Fluid Dynamics. The models were analyzed using SolidWorks Flow Simulation software. The presented dust collectors are real-life objects, applied in industrial facilities. For a multi-cyclone, the increase in the number of blades, from 5 to 8, together with the change in the angle of a blade’s pitch i.e., 30° and 45°, resulted in dust concentration along the internal walls from just 10% for 5 blades up to c.a. 37.5% for 6 blades, and c.a. 50% for 8 blades, whereas the dust concentration in the device’s central part equals c.a. 20% for the last option. The model validation draws attention to the potential applicability of the software in flow issues alongside common and more complex numerical environments.

“…Therefore, researchers have deeply explored the multi-stage dust control and emission reduction linkage control technology. As of now, an integrated dust control system is being developed in mining, such as ventilation and dust discharge (Jiang et al 2021a ; Yu et al 2017 ; Zhou et al 2022 ), wet dust reduction (Peng et al 2020 ; Wang et al 2020d ; Xu et al 2018 ; Zhang et al 2021c ), airtight dust extraction (Chen et al 2022b ; Nie et al 2016 ), purified wind flow (Wang et al 2014 ), and dust suppressant (Li et al 2021 ; Wang et al 2014 ; Zeng et al 2023 ; Zhou et al 2020b ; Zhu et al 2021 ). Cai et al studied the influence of exhaust air volume and forced ventilation height on dust suppression performance of mixed ventilation system (Cai et al 2019 , 2021 ).…”

Dust pollution control is the basic guarantee of mine safety production, which has been widely concerned by scholars. Based on a total of 1786 publications collected by the Web of Science Core Collection (WOSCC) from 2001 to 2021, this paper analyzes the spatial–temporal distribution characteristics, hot topics, and frontier trends of the international mine dust field during the past 20 years by using Citespace and VOSviewer knowledge graph technology. The research shows that the study of mine dust can be divided into three stages: initial period (2001 ~ 2008), stable transition period (2009 ~ 2016), and boom period (2017 ~ 2021). The journals and disciplines which belong to mine dust research mainly focus on environmental science and engineering technology. A stable core group of authors and institutions have been preliminarily formed in the dust research field. The main themes of the study contained the whole process of mine dust generation, transport, prevention, and control, as well as the consequences of disaster. At present, the hot research fields mainly focus on mine dust particle pollution, multi-stage dust prevention, and emission reduction technologies, and mine occupational protection, monitoring, and early warning. In the future, the research should focus on the mechanism of dust production and transportation, the theory of efficient prevention and control, the technology and equipment of precise prevention and control of dust, and the high-precision monitoring and early warning of dust concentration. Future research should be concerned with dust control in underground mines and deep concave open-pit mines with complicated and treacherous environments, and strengthen research institutions, interdisciplinary cooperation, and interaction so as to promote the integration and application of mine dust and automation, information, and intelligent technology.

“…Traditional cyclones are limited to the size of the separation chamber, which changes due to the efficiency of the air being cleaned. Investigations have been performed analyzing the orientation of the inflow opening, the number of inflows, and their geometry and size [29][30][31][32]. This analysis is also possible in multichannel cyclones, but additional purification can be controlled by changing the arrangement of the channels and the shape of the channel-forming elements-research in this area is being conducted [32].…”

The variation in the two-phase flow parameters in a cylindrical body of new geometry and principle of operation are considered for a device for separating solids from air flow, solving the problem of numerical flow modeling. The aim of this research was to analyze the changes in the parameters of a multi-channel cylindrical cyclone in a mathematical model and to compare it with the results of the examined physical model. Studies on the numerical modeling of cyclones are reviewed, and models and equations for complex vortex flow description are applied. Differential equations were numerically solved by the finite volume method using the standard turbulence models of k‒ε and RNG k‒ε. Numerical modeling of the velocities, pressures, and volumes of both phases of the two-phase flow was performed. The simulation of the volume distribution of the second phase (glass particles) in the cyclone structure at flow rates of 10.9 m/s, 13.9 m/s, and 21.9 m/s was performed. The values obtained were compared with the physical model of the cyclone in question. The mean relative error was ± 6.9%.
