Granular flow dynamics encompasses the study of particulate matter in motion which, unlike conventional fluids, display both solid-like and fluid-like characteristics. The field investigates the ...

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 ...

Granular flow dynamics and collapse mechanisms represent a rapidly evolving area of research that spans fundamental physics, geotechnical engineering and natural hazard assessment. At its core, the ...

New findings describe the dynamics of the clog of icebergs -- known as an ice mélange -- in front of Greenland's Jakobshavn Glacier. The fast-moving glacier is considered a bellwether for the effects ...

If static, this problem is straightforward to solve using FE software because the nonmoving material can be treated as a solid. But attempting to simulate the unloading of the hopper would complicate ...

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 ...

There's rarely time to write about every cool science-y story that comes our way. So this year, we're once again running a special Twelve Days of Christmas series of posts, highlighting one science ...

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 ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

Downslope flow: the researchers in the lab with their experiment. (Courtesy: Université Paris-Saclay/FAST) The flow rate of avalanches could be reduced by up to two-thirds by covering vulnerable ...
