Momentum transport in granular flows
Computers & Mathematics with Applications, 2008 We investigate the error induced by only considering binary collisions in the momentum transport of hard-sphere granular materials, as is done in kinetic theories. In this process, we first present a general microscopic derivation of the momentum transport equation and compare it to the kinetic theory derivation, which relies on the binary collision ...

The Study of Three-Dimensional Granular Stream Flowing through the Test Hopper-Shaped Target
Science and Technology of Nuclear Installations, 2020 The experiments are carried out in a three-dimensional channel with a screw conveyor, which plays the role of granular drives for the granular flow system and determines the injection of granular in the test target section. The jam-to-dense transition of

Analysis of the Tangjiaxi landslide-generated waves in the Zhexi Reservoir, China, by a granular flow coupling model [PDF]
Natural Hazards and Earth System Sciences, 2017 A rocky granular flow is commonly formed after the failure of rocky bank slopes. An impulse wave disaster may also be initiated if the rocky granular flow rushes into a river with a high velocity. Currently, the granular mass–water body coupling study is

Experimental study on nonlinear friction behavior of granular flow lubrication
Results in Physics, 2022 Solid granules have good lubrication performance and load-bearing capacity, which has been concerned by researchers. However, the correlation mechanism between lubrication performance and granular medium dynamics is hardly focused on.

Research on the Obstruction Process of Rigid Netting Barriers toward Granular Flow
Advances in Civil Engineering, 2019 With the advantages of a simple structure and rapid construction, the rigid netting barrier (RNB) exerts a good obstruction effect on granular flow and is a common engineering measure used to prevent geological disasters in the form of granular flows ...

Dilatancy in Slow Granular Flows [PDF]
Physical Review Letters, 2009 When walking on wet sand, each footstep leaves behind a temporarily dry impression. This counterintuitive observation is the most common illustration of the Reynolds principle of dilatancy: that is, a granular packing tends to expand as it is deformed, therefore increasing the amount of porous space.

Constitutive relations for compressible granular flow in the inertial regime
Journal of Fluid Mechanics, 2019 Granular flows occur in a wide range of situations of practical interest to industry, in our natural environment and in our everyday lives. This paper focuses on granular flow in the so-called inertial regime, when the rheology is independent of the very

Statistical properties of gravity-driven granular discharge flow under the influence of an obstacle
EPJ Web of Conferences, 2017 Two-dimensional granular discharge flow driven by gravity under the influence of an obstacle is experimentally investigated. A horizontal exit of width W is opened at the bottom of vertical Hele-Shaw cell filled with stainless-steel particles to start ...
