A rotating suspension of 192 settling balls in a horizontally rotating cylinder filled fully
by an incompressible viscous Newtonian fluid: four clusters are formed.
A sequence of animation of the 192 balls spreading out widely initially:
- 0< t < 15:

- 15< t < 30:

- 30< t < 50:

- 50< t < 65:

- 65< t < 80:
