在以前的出版物[O。A. M. Boote和P. J.托马斯,Phys. Fluids 11,2020(1999)10.1063/1.870065],我们描述了在部分填充流体的水平旋转圆柱体内部的颗粒负载流中由颗粒分离发展的新的带型。在这里,我们讨论了长达数周的长期观测,揭示了系统可以显示出极其丰富的时空行为,出现的模式非常缓慢地沿着旋转轴漂移。一些无量纲的关键参数的动态确定。
In a previous publication [O. A. M. Boote and P. J. Thomas, Phys. Fluids 11, 2020 (1999)10.1063/1.870065], we described a new banding pattern developing from particle segregation in particle-laden flow inside a partially fluid-filled, horizontal, rotating cylinder. Here we discuss long-term observations lasting up to several weeks revealing that the system can display an extremely rich spatiotemporal behavior that emerges as the patterns drift very slowly along the axis of rotation. Some of the nondimensional key parameters governing the dynamics are identified.
