Abstract: In the first part, a jointed experimental and numerical study examining the influence of vortical structures on the settling of a cloud of solid spherical particles under the action of gravity at low Stokes numbers is presented. We use electro-convection to generate a two-dimensional array of controlled vortices which mimics a simplified vortical flow. Particle image-velocimetry and tracking are used to examine the motion of the cloud within this vortical flow. The cloud is modeled as a set of point-particles for which the hydrodynamic interaction is preponderant. The cloud behavior (trajectory, velocity, aspect ratio, break-up time . . . ) is compared to the predictions of a two-way-coupling numerical simulation. In the second part, a jointed experimentally and numerical study on the dynamics of slender flexible filaments settling in a viscous fluid at low Reynolds number is presented. The equilibrium state of a flexible fiber settling in a viscous fluid is examined using a combination of macroscopic experiments, numerical simulations and scaling arguments. We identify three regimes having different signatures on this equilibrium configuration of the elastic filament : a weak deformation regime wherein the drag is proportional to the fiber velocity settling perpendicular to the gravity ; a large deformation regime wherein the drag is proportional to the fiber velocity settling parallel to the gravity and an intermediate elastic reconfiguration regime where the filament deforms to adopt a shape with a smaller drag which is no longer linearly proportional to the velocity but to the square root of the velocity.
