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.
