Investigating granular length scales using the Central Limit Theorem We attempt to measure a length scale for correlations among grains in a two-dimensional granular medium. We partition the space, assigning a volume to each grain in the system. By looking at the distributions of clusters of N neighboring grains, we can see how they scale with N. We find that they do not scale in a way compatible with the Central Limit Theorem, indicating that the individual volumes are not independent (i.e. there is a correlation among grains).
