Abstract
EN The work of traditional cyclones is based on the separation of solid particles by using only the centrifugal forces. Therefore, they do not demonstrate high gas cleaning efficiency, particularly, in the cases, when gas flows are polluted with fine solid particles (about 20 µm in diameter). The specific feature of a new generation multi-channel cyclone-separator’ structure is that its symmetrical upgraded curved elements with openings cut with their plates bent outwards make channels for the continuous movement of the gas flows from the inflow opening to the central axis. The smoke flue of the vertical gas outflow is located near the cover of the separating chamber. The present work is aimed at studying the applicability of two various viscosity models and their modified versions to simulate aerodynamic processes in an innovative design of multi-channel cyclone-separator with a single inflow by using the computational fluid dynamics. The research results obtained in the numerical simulation are compared to the experimental results obtained by using a physical model. The main purpose of this study is to provide information on how the new design multi-channel cyclone affects the distribution of gas flow in the cyclone’ channels. The cases of using modified viscosity models, k–ε and k–ω, and computational meshes with various levels of detailed elaboration were analyzed. The developed numerical models of a single-inlet multi-channel cyclone-separator allow the researchers to describe its advantages and possible methods of improving its new structure. The developed models can be used for simulating fluid cleaning phenomenon in the improved fourth-channel cyclone-separator and to optimize the whole research process.
