Granular Flow

Granular flow refers to the movement of particles like grains, sand, or small rocks when they shift under the influence of gravity or external forces. It occurs in natural settings, such as landslides or sand dunes, and in industrial processes like grain storage or pharmaceuticals. The behavior can range from smooth, continuous flow to sudden, unpredictable avalanches, depending on factors like particle size, shape, and how they’re packed. Understanding granular flow helps manage risks and design efficient systems involving loose materials.
