abstract

We consider several rigid bodies immersed in a viscous Newtonian fluid contained in a bounded domain in $R^3$. We introduce a new concept of dissipative weak solution of the problem based on a combination of the approach proposed by Judakov with a suitable form of energy inequality. We show that global--in--time dissipative solutions always exist as long as the rigid bodies are connected compact sets. In addition, in the absence of external driving forces, the system always tends to a static equilibrium as time goes to infinity. The results hold independently of possible collisions of rigid bodies and for any finite energy initial data.

  1. On the impact of clusters of rigid balls on the motion of a viscous fluid

    math.AP 2026-07 accept novelty 7.0 of 10

    A cluster-based method improves the allowable number of tiny rigid balls in a viscous fluid before their collective effect disappears, and shows the balls follow the fluid flow in the limit, even under gravity.
