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 ...

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) ...

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 ...

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 ...

Geophysicists solve a key problem in physics and provide results that can be applied in such diverse areas as planetary research and 3-D printing / publication in ‘PNAS’ The prediction of the angle of ...

Introduction Have you ever seen video footage of an avalanche or landslide rolling down a hill? Why is it that at one moment everything seems fine then suddenly the mountain begins to slump? This ...

The processing of powders is involved in many applications in the food industry. The formulations of recipes typically require the blending of constituents with different properties in terms of ...
