Granular flow dynamics in rotating systems is a multifaceted field that blends fundamental physical principles with practical industrial applications. Rotating drums, mixers and similar apparatuses ...

When we take a stroll on the beach, we walk on the sand without any trouble. The sand appears solid and is difficult to compress. When we put the same sand grains in an hourglass, they behave very ...

Suppose a hopper is filled with a granular material such as sand, and you need to compute the force or stress on the hopper walls. If static, this problem is straightforward to solve using FE software ...

MADISON - A handful of sand contains countless grains, which interact with each other via friction and impact forces as they slip through your fingers. When a handful becomes a load in an excavator ...

video: In their work on microrobotic microrollers, researchers in Lehigh University's Laboratory of Particle Mixing and Self-Organization showed that the negative angle of repose (uphill flow) results ...

Nalini Easwar's field of interest is experimental condensed matter physics, specifically complex fluids such as macromolecular solutions, colloids and granular systems. Her current work focuses on ...

Fine powders and granular materials are used across a broad spectrum of industrial applications. To optimize and control processing methods, these materials have to be characterized with great ...
