摘要
We have built experimentally and have numerically studied sandpiles on a base having a prefractal perimeter. This type of perimeter induces the formation of quite complex pile shapes characterized by both ridges and valleys. The effects of a fractal base on the phase segregation of a binary granular system have been investigated. Both demixing and self-stratification phenomena have been investigated. It is found that the demixing of binary granular piles is enhanced by the prefractal perimeter character. The concentration profiles are given. This is briefly discussed in terms of length scale selection. [S1063-651X(98)14412-4].
