摘要：In this paper, the computational particle fluid dynamic (CPFD) numerical scheme was applied to simulate the discharge of glass bead from a 3-D hopper. The flow snapshots and the solid discharge rates were captured by the CPFD method and compared with the experimental results; the solid volume fraction, particle and gas velocities, and pressure in the hopper were given by the CPFD model and discussed detailedly; the effect of hopper structure on powder discharge was discussed based on the CPFD method. The investigation confirms that CPFD has become an essential and valuable tool to identify particles and gas dynamic properties in the hopper.
