摘要
用离散元程序(PFC2D)研究了筒仓卸料过程贮料颗粒的流型、速度场、力场以及仓壁侧压力的变化,并与实验结果进行比较。离散元模拟测得筒仓静、动侧压力与实验值基本吻合,且取得了理论方法和常规实验所不能取得的信息。
The discrete element method (Particle flow code in 2-dimensions) was used to study particles flow style, velocity fields, internal contact forces and the lateral pressure of silo wall. Some information such as the internal contact forces and velocity fields which cannot get by theoretic method and experiment were obtained. Both smile pressure and dynamic pressure detected by the method of discrete element simulation were in good agreement with the experimental results.
