A numerical model of gas flow in a direct-flow cyclone of two different configurations is presented. The main task of the simulation was to determine the gas velocity field in the apparatus and analyze the presence of a turbulent wake of the stabilizer swirled, which can have a negative impact on the efficiency of the apparatus. During the study, it was found that when the gas flow is disrupted by the stabilizer of the swirler, a turbulent wake is formed, into which trapped particles can fall. The solution to this problem is to lengthen the stabilizer and increase its diameter. The article also discusses numerical studies of cyclones, devices for purifying gases from dust known in the literature. The review showed the popularity of such topics among scientific teams, which confirms its relevance. Publications include numerical models of vehicles, which are obtained using various turbulence modeling methods. The most significant result of numerical modeling is the gas velocity field, on the basis of which the efficiency of the devices is determined, and their design is optimized and modernized. A brief overview of the most well-known turbulence models is given, and their main advantages and disadvantages are described. It has been shown that the ratio of accuracy and demand for computing resources of RANS models is justified in most cases. Based on a review of models, the choice of a turbulence model for the ongoing numerical study of a new design of a direct-flow cyclone is justified.
