Granular avalanches in fluids.
Three regimes of granular avalanches in fluids are put in light depending on the Stokes number St which prescribes the relative importance of grain inertia and fluid viscous effects and on the grain/fluid density ratio r. In gas (r>>1 and St>1, e.g., the dry case), the amplitude and time duration of avalanches do not depend on any fluid effect. In liquids (r approximately 1), for decreasing St,...
متن کاملRapid Granular Avalanches
Granular avalanches are one of the fundamental grain transport mechanisms in our natural environment and in many industrial grain-processing flows. In recent years significant progress has been made in describing the flow of granular avalanches over complex rigid topography. Often the fluid-like granular avalanches flow over a region of solid-like grains at which there may be erosion or deposit...
متن کاملDynamics of dry granular avalanches.
A fine analysis of the statistics of dry granular avalanches in a rotating drum setup reveals that, beyond the fluctuations, the angle at which an avalanche ends is correlated experimentally to the angle at which the avalanche starts. This correlation resulting from inertia defines an intermediate "neutral" angle that characterizes the corresponding granular pile. In addition, an intensive stud...
متن کاملField Strength Prediction in Irregular Terrain – the PTP Model
This report describes a prediction technique for the calculation of the field strength of radio waves over irregular terrain paths. The concept of an "equivalent rounded obstacle" is used to account for radio propagation losses over various possible irregular terrain shapes, including shapes which cannot easily be described geometrically. The technique replaces an arbitrary terrain profile with...
متن کاملParticle Image Velocimetry (PIV) for Granular Avalanches on Inclined Planes
This paper is concerned with experimental results of sand avalanches flowing down inclined plexiglass chutes with lateral confinement. Specifically we introduce the particle image velocimetry (PIV) technique for granular avalanches. We discuss the differences and problems in comparison with “usual” PIV. After this, we present surface and side velocity measurements that are obtained at different...
