On the impact of clusters of rigid balls on the motion of a viscous fluid
Marco Bravin, Eduard Feireisl, Arnab Roy +1
We develop a new approach to the problem of the motion of a large number of rigid bodies immersed in a viscous fluid. The leading idea is the concept of cluster - a collection of i…

On the long time behaviour of a system of several rigid bodies immersed in a viscous fluid
Marco Bravin, Eduard Feireisl, Arnab Roy +1
We consider several rigid bodies immersed in a viscous Newtonian fluid contained in a bounded domain in . We introduce a new concept of dissipative weak solution of the proble…

On the collective effect of a large system of heavy particles immersed in a Newtonian fluid
Marco Bravin, Eduard Feireisl, Arnab Roy +1
We consider the motion of a large number of heavy particles in a Newtonian fluid occupying a bounded spatial domain. When we say "heavy", we mean a particle with a mass density tha…
