Pedestrian collective motion in competitive room evacuation
When a sizable number of people evacuate a room, if the door is not large enough, an
accumulation of pedestrians in front of the exit may take place. This is the cause of emerging …

DEM study in the critical height of flow mechanism transition in a conical silo
Y Zhang, F Jia, Y Zeng, Y Han, Y **ao - Powder Technology, 2018 - Elsevier
The discharging in silo presents the characteristics of mass flow in the upper part and funnel
flow in the lower part. Obviously, there is a special position where the flow pattern transition …
