| Abstract: |
A new semi-underground double-storey squat silo (SUDSSS) with high storage quality and carbon reduction was proposed. In this paper, a numerical model was established by comprehensively employing finite and discrete element methods to investigate the discharging dynamic interaction between particles and silo. The model's validity was verified by comparing the numerical simulation results and the theoretical values. The central discharging performance and the effects of t different particles on the lateral pressure were investigated. The results indicate that: (1) Surge and oscillation of the lateral pressure were observed during discharging. The stresses in each storey reach the maximum at 1/4 of the distance from the bottom; (2) The maximum lateral pressure decreases as the discharging rate decreases and overpressure tends to occur in the middle of the silo wall (3) It was concluded that the dynamic pressure was significantly correlated with the coefficient of rolling friction of particles. [Display omitted] • Investigate the dynamic interaction between particles and silo during discharging • Investigate the stress and lateral pressure of silo during discharging • Analyze the effect of discharging rate on the lateral pressure at the silo wall • Investigate the effect of different particles on the lateral pressure • Analyze the correlation rankings of the influencing factors of the dynamic pressure [ABSTRACT FROM AUTHOR] |
