The Four Avalanche Fronts: a Test Case for Granular Surface Flow Modeling
نویسندگان
چکیده
Granular surface flows have still to be fully modelled. Here, we present the four types of front that can be observed in avalanches. These strongly inhomogeneous and unsteady flows are very sensitive test cases for the different types of model. We show that, at least qualitatively for the moment, the model we propose, based on the analysis of the motion of a single grain and layers of grains, can reproduce the different characteristics of these four fronts.

A Model of Granular Flows over an Erodible Surface
We present a framework for modeling a dry geophysical mass of granular material – a debris or volcanic avalanche or landslide – flowing over an erodible surface. We also describe a computing environment that incorporates topographical data into a parallel, adaptive mesh computational algorithm that solves the model equations.
متن کاملCFD Modeling of the Feed Distribution System of a Gas-Solid Reactor
Granular flow simulation using CFD has received a lot of attention in recent years. In such cases, CFD is either, coupled with Discrete Element Method (DEM) techniques for appropriate incorporation of inter-particle collisions, or the Eulerian CFD approach is used in which granular particles are treated as they were fluid. In the present study, a CFD analysis was performed...
متن کاملChannelized free-surface flow of cohesionless granular avalanches in a chute with shallow lateral curvature
A series of laboratory experiments and numerical simulations have been performed to investigate the rapid fluid-like flow of a finite mass of granular material down a chute with partial lateral confinement. The chute consists of a section inclined at 40◦ to the horizontal, which is connected to a plane run-out zone by a smooth transition. The flow is confined on the inclined section by a shallo...
متن کاملGranular forces from steady and avalanche flows on a wall-like obstacle: contribution to avalanche dam design
The present paper deals with the hydrodynamic force from granular streams overflowing a wall-like obstacle. An analytical continuum model is proposed to derive this force both for steady and unsteady flow conditions. The force derived from the continuum model is successfully compared to the time-averaged force from discrete numerical simulations of free-surface granular flows down an incline an...
متن کاملGranular flow in partially filled slowly rotating drums
In many industrial processes granular materials are mixed together in partially filled slowly rotating drums. In this paper a general theoretical framework is developed for the quasi-two-dimensional motion of granular material in a rotating drum. The key assumption is that the body can be divided into a fluid-like and a solid-like region, that are separated by a non-material singular surface at...
