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 ...

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 ...

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 ...

In this experiment, we explore the strange behavior of granular materials, how tiny grains can appear to defy gravity, flow ...

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 ...

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 ...

Wearable or implantable devices to monitor biological activities, such as heart rate, are useful, but they are typically made ...

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 bucket, ...
