Discrete element method is one of the most common methods to simulate granular flow. The material properties used are quite influential on the results. In this project, some experiments are performed to measure friction coefficients. The accuracy of the measured friction coefficients is confirmed by the test of angle of repose and hopper flow. Various experiments have been carried out to measure the coefficient of static friction and the coefficient of friction between particles and particles and between particles and containers. Also, to confirm the accuracy of the friction coefficient obtained by the experiment, the discharge amount of the actual hopper measured by PIV was compared with the discharge amount of the DEM simulation.

I felt that EDEM had a more convenient interface than other commercial software. I also think that the simulation analysis time is fast.
