We consider the motion of N rigid bodies – compact sets (Sε1,⋯,SεN)ε>0 – immersed in a viscous incompressible fluid contained in a domain in the Euclidean space Rd, d=2,3. We show the fluid flow is not influenced by the presence of the infinitely many bodies in the asymptotic limit ε→0 and N=N(ε)→∞ as soon as diamSεi→0asε→0,i=1,⋯,N(ε). The result depends solely on the geometry of the bodies and is independent of their mass densities. Collisions are allowed and the initial data are arbitrary with finite energy.
