The collapse of a granular column confined in a vertical annulus is investigated through both
experiments and DEM. During the collapse of column, an outward-moving avalanche and a …

The breaking of dam can cause sudden debris flow which leads to hazardous
consequences. This paper presents a coupled Computational Fluid Dynamics and Discrete …

Granular flows have been the subject of several researches in the last years, not only in
fluvial hydraulics and risk management but also in many other engineering applications …

In this paper a dry granular dam break phenomenon is investigated comparing experimental
and numerical results. The experiments were performed reproducing the sudden collapse …

Dam-break flows of granular materials exhibit a complex non-Newtonian rheology, which is
strongly influenced by various factors, such as the characteristics of the granular material …

Granular flows are related to several engineering applications and, thus, widely investigated
in the last decades, for example in disaster prevention and risk management to prevent or …
