我们用数值模拟研究了颗粒气体的流体动力学。我们证明了线性稳定性分析预测的剪切和聚类不稳定性的外观,并表明它们的外观是直接相关的碰撞在材料中的非弹性。我们讨论这些不稳定性出现的速度和集群的增长和合并的方式。
We examine the hydrodynamics of a granular gas using numerical simulation. We demonstrate the appearance of shearing and clustering instabilities predicted by linear stability analysis, and show that their appearance is directly related to the inelasticity of collisions in the material. We discuss the rate at which these instabilities arise and the manner in which clusters grow and merge.
