Segregation Mechanisms and Their Quantification Using Segregation Testerserties, one often encounters a phenomenon called segregation. Segregation is a tendency for certain sizes, or components with similar properties, to preferentially collect in one or another physical zone of a collective. This tendency to separate into different zones is largely caused by differences

Particle Segregation in Granular Flows Down Chuteschutes show the relative importance of segregation mechanisms. In uniform steady flow experiments with binary mixtures of small and large particles, the small particles fall downward and the large particles migrate upward. In slow, dry, frictional flows, the downstream segregation is so efficient th

Study on the Mixing of Discs in a Galton’s Device as a mechanism allowing mixing..A Galton’s device consists essentially in a regular array of obstacles that can modify the direction of movement and velocity of a falling particle (bead or disc), each time the particle collides with an obstacle. In this kind of system the particle flies freely unti

Size Segregations in Snow Avalanches1]. It is well known that the snow cloud sometimes travels faster and farther than the flowing part and may cause serious damage in the runout area. However, since the dense flow often involves most of the mass of the avalanche and is very destructive, understanding its characteristics is of practic

Microgravity Segregation in Collisional Granular Shearing Flowsation energy of the grains..Experiments were conducted on NASA’s microgravity aircraft with a shear cell shaped like a race track and containing a mixture of two types of spherical grains. A gradient of fluctuation energy was produced between the inner, energetic moving boundary driving collisions a

Segregation of Binary Mixtures in a Vertical Shaker shaker for a certain range of vibrational accelerations. The segregation effect was more significant for the mixture with larger size difference. The segregation coefficient was measured and found to increase with the vibrational acceleration until reaching a maximum and then to decrease with the a
