摘要: Drag force coefficient is crucial for modelling gas-solid flows in using Discrete Element Method (DEM). Previous studies seldom concern about the mathematical properties of this coefficient, and just take it as a homogenous function. In paper, demonstration carried out to prove that drag 2nd order tensor, indicate can be reduced Then, seven kinds coefficients adopted by MFIX are listed. Finally, all listed assessed simulating granular slot-rectangular spouted bed. Comparing simulated velocities particles with experimental data region, different analysed find which one best model
