Optimization of granular chute flow with two bottlenecks

Granular materials are ubiquitous in industrial, mining and pharmaceutical processes. In this paper, we study the flow pattern and optimization of granular chute flow with two bottlenecks. The dependence of flux on channel width show dilute to dense flow transition. A remarkable bistable phenomenon...

Description
Summary:Granular materials are ubiquitous in industrial, mining and pharmaceutical processes. In this paper, we study the flow pattern and optimization of granular chute flow with two bottlenecks. The dependence of flux on channel width show dilute to dense flow transition. A remarkable bistable phenomenon appears near the transition point. Base on this discovery, one can optimize the flow rate along such channels.
