Description
We present simple computer algorithms able to build random packings of spheres using the ballistic deposition model and we show how they can be used to investigate several size segregation phenomena occuring in granular systems: 1) penetration of a small sphere in a packing of large ones, 2) size-segregation in the formation of a heap or when pouring a silo, 3) size-segregation by shaking. In the last case, the computer simulation provides a very simple geometrical explanation of the phenomenon. (orig.)
