摘要

A screw powder feeder is an important device for industrial applications. There are many parameters which affect the performance of the screw powder feeder, such as the shapes of the helical screw impeller, the number of screw pitches, etc. This paper presents an analysis of a gas-solid two-phase through screw powder feeder by using a commercial Computational Fluid Dynamics（CFD） code, Fluent. The K-ε model is used to simulate gas flow. Particle trajectory is obtained by the use of a discrete phase model. The results show the effects of gas velocity and panicle size on the transportation performance.
