Title: Sedimentation of a cloud of spheres at low Reynolds number - I Description: This movie shows the bottom view of a settling cloud of spheres in a viscous fluid. The cloud is initially spherical. It then develops a toroidal circulation similar to that observed for a heavy fluid drop falling in an otherwise lighter fluid. However the spherical cloud of particles is unstable; it evolves toward a torus which further destabilizes into secondary droplets (see other movies). Credits: B. Metzger, M. Nicolas, E. Guazzelli
