The numerical simulation is performed on the gas-phase flow field in vertical screw type conveyer based on computational fluid dynamics technologies, and the sliding grid is used to simulate rotation of the helical blade.At three different speeds, fixed-point observation is performed on the pressure and speed in the conveyor to get the variation trend of both pressure and speed under different speeds, providing certain guidance for further gas-solid phase flow analysis.
