About this Engineering article
Numerical Simulation of Particle Flow Behavior in a Screw Conveyor Using the Discrete Element Method by Shuyan Wang; Haolong Li; Ruichao Tian; Ruichen Wang; Xu Wang; Qiji Sun; Jiawei Fan is a Engineering article available to read on EtoBox.
Particle motion in a screw conveyor was simulated with the discrete element method. The particle flow behavior and transport processes at different screw rotating speeds and filling levels were investigated in this study. The spatial distributions of particle velocity were predicted. The predicted mass flow rate increased with increasing screw rotating speed and filling level. The contact forces and granular temperatures of particles were also calculated. The simulation results showed that the translational granular particle temperatures were higher than the rotational granular particle temperatures. In addition, the configurational temperatures of particles were calculated from simulated instantaneous particle overlaps, and results indicated that deformation of elastic particles contributed to the rate of energy dissipation. Good agreement between the numerical simulation and experimental results was achieved in this study.
