Measurement and simulation validation of DEM parameters of pellet, sinter and coke particles

Numerical Analysis of the Relationship between Friction Coefficient and Repose Angle of Blast Furnace Raw Materials by Discrete Element Method

“…Four experimental materials are involved in the experiments: pellet, sinter, coke and steel plate. Their basic parameters are shown in Table 2 [ 27 ]. This work only changes CORF and COSF of one contact surface of the experimental group.…”

“…This work only changes CORF and COSF of one contact surface of the experimental group. The friction coefficients of other contact surfaces are fixed and the parameters are shown in Table 3 [ 27 ].…”

“…After determining the calculation model, selecting the physical geometry and initial conditions, the physical parameters have to be selected appropriately as they are very important for the accuracy of the simulation results by DEM. At present, in addition to laboratory measurements [ 26 , 27 ], the use of DEM to estimate physical parameters has become an established method [ 28 , 29 , 30 ]. However, the DEM parameters of blast furnace raw materials (pellet, sinter and coke) have not been well characterized.…”
