Abstract

Slope angle and porosity are two important parameters to describe granular stockpile which is related closely to some phenomena in nature and various industries. In order to study influence of particle physical parameters to the shape, slope angle and porosity of the pile, corn pile experiments and calculations were investigated. The results showed that once physical parameters are chosen properly, simulation results are in good agreement with experimental ones. Particle density, Young's modulus and Poisson's ratio have little influence on the shape, slope angle and the porosity of the pile. Coefficient of restitution has some effects on the slope angle and porosity, which both decreases with the increase of restitution coefficient. Furthermore coefficient of static and rolling friction have obviously effects on the shape, slope angle and porosity of the pile and all this properties are more sensitive to the former.
