Abstract: | Tthe mass movement of fine particles and changes in their trajectories under the effect of centrifugal, gravitational, and
aerodynamic forces is studied by numerical modeling of turbulent swirling flow. The effect of turbulent migration of solid
particles due to pulsating gas flow velocities on the aerodynamics of particles and, consequently, on the efficiency of the
process of separation of particles by size is analyzed. The studies revealed the behavior laws of probability curve of separation
of particles by size and showed the effect of regime and geometric parameters on the process of classification of fine powders. |
