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

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 ...

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 ...

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 ...

Granular materials and fine powders are commonly utilized in industrial applications. For the control and optimization of processing procedures, such materials need to be characterized in a precise ...

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 ...
