Some typical streams Segregation induced by vibrations When we shake a granular medium, large grains go up. You have certainly noticed this phenomenon by looking at the previous animations concerning convection. Now we increase the difficulty by modeling grains with polygons. Flows We simulated flows of media composed of particles having varying properties in order to see their influence on the flow time. In the experiment below, we compared four media composed.
Curves depict the percentage of grains passed in terms of time.
Incline of walls is 30 degrees with respect to vertical. Shape has no effect. We simulated the penetration of a body inside a granular medium. Contrary to the previous simulations, we used here the soft-particle model, more precisely Cundall's model. The large disc is falling down from a height of 23 m.
