Fine powders and granular materials are extensively used in industrial applications. To manage and to enhance processing techniques, these materials have to be exactly characterized. The ...

An audit will tell you how much stuff came down and how fast, but only a real understanding of the whole environment will reveal at what point it all stabilizes and comes to rest, how high the piles ...

A heap is created when a powder is poured onto a surface. It is widely known that both the heap shape and the repose angle strongly rely on grain properties. Specifically, a non-cohesive powder forms ...

The prediction of the angle of repose for raised mounds of dry cohesive granular material is a long-standing problem in the natural sciences and in industry. Using numerical (particle-based) ...

Growing up in a household where there was plenty of exposure to home construction cultivated a fascination with dirt and sand piles, necessary components of many varied projects in which a parent was ...
