Abstract
We report results from a statistical analysis of avalanches of cohesive pow ders in a slowly rotated drum. Interparticle adhesion, which diminishes the effect of inertia and whose magnitude strongly fluctuates in a local scale , makes avalanches in slightly cohesive powders eligible for displaying sel f-organized criticality. However, the results show that avalanche sizes, ti me interval between avalanches, and maximum stable angle do not follow a po wer-law distribution. Otherwise, these parameters scale with powder cohesiv eness.
