论文摘要
我们在实验上研究了空气荧光盘的二元混合物的动力学。这些磁盘是手性的，因为它们结合了一组持续倾斜的刀片。这两个物种都是相同的，除了它们的叶片倾斜角，第二种在第二种中旋转180o。我们分析系统的相行为。我们的分析揭示了各种不同的流体动力学，包括手性流动。这种手性流在其基本状态下具有巨大的涡流。我们报告，对于每种物种的相对颗粒密度的某些范围，是该涡旋的涡度反转。我们讨论了这些手性流过渡背后的可能机制。
We study, experimentally, the dynamics of a binary mixture of air-fluidized disks. The disks are chiral since they incorporate a set of blades with constant tilt. Both species are identical except for their blades tilt angle, which is rotated by 180o in the second species. We analyze the phase behavior of the system. Our analysis reveals a wide range of different fluid dynamics, including chiral flow. This chiral flow features in its base state a large vortex. We report, for certain ranges of relative particle density of each species, inversion of the vorticity of this vortex. We discuss on the possible mechanisms behind these chiral flow transitions.
