摘要: Abstract In this Letter, we present the results of our study on influence granule velocity granular flow state. The maximum outflow rate dilute state increases with an increase in velocity, whereas dense remains unchanged. addition, increasing can extend region and shrink that These observations be explained by relationship between packing fraction at bottleneck under a fixed particle number condition.
