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 ...

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 ...

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 ...

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 ...

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 ...

Physicists have long known that the flow of sand through an hourglass is entirely different from the flow of liquid. In the case of a liquid, the rate of discharge depends on the pressure at the ...

Researchers at the University of Illinois Urbana-Champaign have developed a novel framework for understanding and controlling the flow behavior of granular hydrogels—a class of material made up of ...

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 ...

Users import a CAD model of their machine into EDEM in IGES, STEP, or a native CAD file format, where it is converted into a surface mesh. Suppose a hopper is filled with a granular material such as ...
