Bi-disperse particle-laden flows in the Stokes regime
  This arXiv article describes the fluid dynamics video on `Bi-disperse particle-laden flows in the Stokes regime', presented at the 65th Annual Meeting of the APS Division of Fluid Dynamics in San Diego, CA in November 2012. The video shows three different experiments which aim to investigate the dynamics of a thin film of silicone oil, laden with glass beads and the effects of adding a second species of particles to the slurry. The mixture of oil and particles is allowed to flow down an incline under the action of gravity. The videos were recorded at the UCLA Applied Math Laboratory.
