“…On an inclined plane, disorderedto-ordered flow transition is observed when changing the basal * humaobin@ustc.edu.cn † mayhou@iphy.ac.cn roughness [24]. In a channel with two successive bottlenecks, a bistable phenomenon of dilute and dense flow state is discovered when the channel width is properly adjusted [25,26].…”

Merging of granular flows is ubiquitous in industrial, mining, and geological processes. However, its behavior remains poorly understood. This paper studies the phase transition and flow-rate behavior of two granular flows merging into one channel. When the main channel is wider than the side channel, the system shows a remarkable two-sudden-drops phenomenon in the outflow rate when gradually increasing the main inflow. When gradually decreasing the main inflow, the system shows obvious hysteresis phenomenon. We study the flow-rate-drop phenomenon by measuring the area fraction and the mean velocity at the merging point. The phase diagram of the system is also presented to understand the occurrence of the phenomenon. We find that the dilute-to-dense transition occurs when the area fraction of particles at the joint point exceeds a critical value ϕ(c)=0.65±0.03.

“…Granular materials are ubiquitous in natural, industrial, mining and geological processes. While they are comprised of many solid particles, their bulk properties exhibit many nonlinear phenomena such as force chains, [1][2][3] surface waves and surface instability, [4,5] resistance to penetration, [6] segregation, [7,8] jamming and clogging, [9][10][11][12] granular flow, [13][14][15] granular clock, [16,17] stress fluctuation, [18] etc. Fluidized beds have been widely used in industry for processing granular materials, such as hydrocarbon cracking, coal gasification, drying and mixing, and so on.…”

Fluidized beds have been widely used for processing granular materials. In this paper, we study the effect of plasma on the fluidization behavior of a bubbling fluidized bed with an atmospheric pressure plasma discharger. Experiment results show that the bubbling fluidized bed is stabilized with the discharge of plasma. When the discharge current reaches a minimum stabilization current Cms, air bubbles in the bed will disappear and the surface fluctuation is completely suppressed. A simplified model is proposed to consider the effect of electric Coulomb force generated by the plasma. It is found that the Coulomb force will propel the particles to move towards the void area, so that the bubbling fluidized bed is stabilized with a high enough plasma discharge.
