SIMULATION OF GAS-SOLID FLOW IN A TRANSFER CHUTE BASED ON CFD-DEM COUPLING METHOD

摘要：

　　This paper focuses on the simulation of gas-solid two-phase flow in the transfer chute based on the coupled CFD-DEM method.The Computational Fluid Dynamics(CFD)is used to solve the gas phase through the open source software OpenFOAM.Discrete Element Method(DEM)is used to solve the particulate flow,through the open source software LIGGGHTS.This method can simulate the complex gas-particle,particle-particle and particle-wall interaction in the transfer chute at mesoscopic scale.Compared with the previous experimental results,the maximum error is 13%.It proves that the method can be used to analyze the gas-solid two-phase flow in the transfer chute.
