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 ...

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 ...

SIAM Journal on Applied Mathematics, Vol. 62, No. 4 (Apr., 2002), pp. 1414-1436 (23 pages) We present a two-dimensional cellular automata network applied to granular flow and often called a ...

Sand in an hourglass might seem simple and straightforward, but such granular materials are actually tricky to model. From far away, flowing sand resembles a liquid, streaming down the center of an ...

Simulations of granular flow dynamics could be particularly useful for vehicle design. The team has worked with P&H Mining Equipment in Milwaukee, which builds three-million-pound electric shovels to ...

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 ...

Treating grains like grains, and not water, could help eliminate blockages, increase productivity and save cash. In the pharmaceutical and food industries, one major roadblock to operational ...

Introduction Have you ever poured sand out of a bucket or cereal out of a box and noticed it seems to flow' a lot like water? This is because both sand and cereal are granular materials. That means ...

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 ...

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 ...

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 ...
