The Study of Three-Dimensional Granular Stream Flowing through the Test Hopper-Shaped Target

Figure 6

Experiment flow snapshots were taken with a high-speed camera: (a–d) interface between dilute flow and dense flow rose with time. (d–f) interface declined with time. (a) and (f) the lowest location of the interface. (d) The highest location of the interface. (b), (c), and (e) the middle location of interface at different time.
