| Abstract: | Avalanche in the chute has been studied to examine how the sizes of granules affect the angle of repose θ r when the width of the chute is fixed. The results show that the angle of repose in the chute has exponential decay with λ, which is the reciprocal of granular diameter d. The fluctuation of the angle of repose is also studied during the chute being tilted, and the results indicate that the fluctuation of the angle of repose increases with the increase of granular diameter d.
