Settling motion of interacting solid particles in the vicinity of a plane solid boundary

International audienceThe sedimentation of N=1 small arbitrarily-shaped solid bodies near a solid plane is addressed by discarding inertial effects and using 6N boundary-integral equations. Numerical results for 2 or 3 identical spheres reveal that combined wall-particle and particle-particle interactions deeply depend on the cluster's geometry and distance to the wall and may even cancel for a sphere which then moves as it were isolated.
