The influence of outlet setting on the discharge dynamics of granular material in 2D moving beds was investigated by conducting discrete element simulations. To validate the simulation

a moving bed with single outlet was first modeled. The simulation results showed that the variation of discharge rate was tally with the modified Beverloo

and the variation tendency of the width of funnel zone was in agreement with the experimental data. Based on such validation

the discharge characteristics of granular material in the moving bed with two outlets were then systematically investigated. The simulation results indicated that as to the bed with two same size outlets

the width of funnel zone was simply equal to the sum of the width of funnel zone of the moving bed with one same size outlet

the distance between outlets and the width of outlet

and the granular mass discharge rate was roughly equivalent to that of the moving bed with one same size outlet. For the bed with two different size outlets

increasing the width of large outlet or decreasing the outlet distance was conducive to increasing the discharge rate at small outlet. Nevertheless

the discharge rate at large outlet was not influenced by the small outlet and nearly kept constant.
