Simulation of the effect of defence structures on granular flows using SPH
defence structures granular flows SPH
2009/12/9
This paper presents the SPH (Smoothed Particles Hydrodynamics) numerical method adapted to complex rheology and free surface flow. It has been developed to simulate the local effect of a simple obstac...
Experimental investigation on steady granular flows interacting with an obstacle down an inclined channel: study of the dead zone upstream from the obstacle. Application to interaction between dense snow avalanches and defence structures
Experimental investigation steady granular flows the dead zone upstream dense snow avalanches defence structures

An experimental investigation with dry granular flows passing over an obstacle down a rough inclined channel has been performed. The aim is to improve our understanding of the interaction between dens...
Energy considerations in accelerating rapid shear granular flows
Energy considerations rapid shear granular flows

We present a complete expression for the total energy associated with a rapid frictional granular shear flow down an inclined surface. This expression reduces to the often used energy for a non-accele...
