谷物压实
Compaction of cereal grain
摘要：
我们报告简单的振荡实验，以衡量压实的一列弗斯燕麦颗粒。这种颗粒是具有双峰多分散性的细长各向异性颗粒。在这些实验中，颗粒的配置开始从一个最初的无序，低包装分数的状态，并在垂直振动下发展到一个密集的状态，在约束管的表面的向列相结构的证据。这伴随着颗粒的堆积分数的增加。
英文摘要：
We report on simple shaking experiments to measure the compaction of a column of Firth oat grain. Such grains are elongated anisotropic particles with a bimodal polydispersity. In these experiments, the particle configurations start from an initially disordered, low-packing-fraction state and under vertical shaking evolve to a dense state with evidence of nematic-like structure at the surface of the confining tube. This is accompanied by an increase in the packing fraction of the grain.
