本文介绍了一种研究稠密流体分子流体力学过程的实验性模拟方法。该技术采用振动、高恢复力颗粒桩的粒子图像测速, 并允许对强相互作用、高密度气体和液体中已知和预测的动态过程进行直接、宏观的观察。

该程序的总体目标是使用模拟技术研究液体中的分子尺度流体动力学过程,该技术测量振动颗粒堆中的单个和集体粒子动力学。该技术的主要优点是它为直接观察复杂的分子尺度动力学提供了实验上可访问的反相微壳层。由于该技术在相互作用粒子系统的统计力学中强耦合,因此它为该领域基本问题的实验研究打开了一扇门。

这项技术还可以用于研究相互作用的宏观粒子系统的统计力学,例如我们正在研究的振动谷物堆。通常,使用这种技术的人将难以学习平衡和非平衡统计力学的要素,这些要素对于在设计实验中解释实验观察是必要的。该技术的视觉演示至关重要,因为它将通常用于测量微米级颗粒运动的粒子成像测速扩展到厘米级颗粒的运动。
