A many-body lubrication model. (English. Abridged French version) Zbl 0898.76019
We present direct numerical simulation of the motion of solid particles in a viscous fluid. We introduce a lubrication model to handle “near collisions”. The objective is to couple this approach with the global computation of the flow. We observe the motion of a close-packed arrangement of particles in a fluid, such that the influence of the fluid on the global behavior is restricted to lubrication forces.
