Granular avalanche statistics in rotating drum with varied particle roughness
We experimentally investigate the avalanche statistics of dry granular materials in a slowly rotating drum for five types of beads with varied surface roughness. For all beads, two distinct angles, i.e., repose angle $\theta_r$ and maximal angle $\theta_m$, can be clearly defined, and the avalanche...
