The numerical simulation analysis about different particles driven by rotation inertia force in rotating cylindrical flow

This paper adopts DPM model to analyze the numerical simulation of particles with several densities and sizes in rotating cylindrical flow and explore the movement features and stress rule of single particle in rotating cylindrical flow. The result demonstrated that when single particle rotate at a constant speed in the flow, it does centrifugal movement, and the speed is getting greater. When the speed ω>10r/min, the rotation inertia force F≥0.1×10 -6 N, and centrifugal force is over one order of magnitude than rotation inertia force. When the speed ω≤10r/min, the rotation inertia force F≤0.1×10 -6 N, and centrifugal force and rotation inertia force are at the same order of magnitude.
