“…These models are based on the hypotheses of Boussinesq [3], Kolmogorov [4], Prandtl [5], Carman [6], etc. The NASA turbulence database [7] provides a comparative analysis of various semi-empirical models. From this analysis we can conclude that the models of Spalart and Allmaras [8], and Menter k−ω SST [9][10][11] have the highest ratings.…”

The article presents a study of the SST turbulence model in the Comsol Multiphysics software package for the problem of a two-dimensional channel with complex geometry. In this work, the finite element method is used for the numerical implementation of the turbulence equations. The implementation of the Comsol Multiphysics 6.1 software package showed good convergence, stability and high accuracy of the SST turbulence model.

“…6, it can be seen that both dust collectors completely capture particles larger than 7 microns. The advantage of the modified [8] dust collector is manifested for particles smaller than 7 microns. For example, for particles of 4 microns, a classic centrifugal dust collector captures only 2%, and a modified centrifugal dust collector 60%.…”

A cyclone separator is an equipment that separates particles contained in a liquid or gas without filters. Dust particles in flue gases can be separated using centrifugal forces and different particle densities so that the exhaust gases must be cleaned before being discharged into the environment. The selection of optimal geometric dimensions and operation parameters of industrial equipment is always a topical issue. In the work, numerical modeling and research of a modified centrifugal cyclone dust collector are carried out. A modified centrifugal cyclone was developed by one of the article's authors at the Institute of Mechanics and Seismic Resistance of Structures of the Academy of Sciences of the Republic of Uzbekistan, which has a high efficiency of at least 98%. The study was carried out in the Comsol Multiphysics 5.6 engineering software package using the Flow Simulation add-on, designed to simulate hydrodynamic processes. The relevance of the chosen research topic was indicated. The standard k-ɛ model is chosen as a turbulence model, which is often used in engineering problems. The computational experiment was carried out at three flow rates in the centrifugal cyclone. Based on the obtained numerical data, it is shown that the efficiency of the modified cyclone is significantly higher than that of the classical cyclone.
