Abstract The overflow behavior of polydisperse granular flows against closed type barrier is a crucial yet poorly understood aspect of multiple-barrier design. We use a robust numerical model based on the three-dimensional discrete element method to simulate polydisperse granular flows and identify fundamental mechanisms. The morphology of the dead zone behind the upstream barrier significantly influences the overflow behavior of granular flows. This implies that aside from the case of a gentler barrier (

多分散颗粒流对封闭式屏障的不稳定溢流行为

摘要 多分散颗粒流对封闭式屏障的溢流行为是多屏障设计的一个关键但知之甚少的方面。我们使用基于三维离散元方法的稳健数值模型来模拟多分散颗粒流并确定基本机制。上游屏障后面死区的形态显着影响颗粒流的溢流行为。这意味着除了更温和的屏障(
