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%.
