Approximate controllability of Lagrangian trajectories of the 3D Navier–Stokes system by a finite-dimensional force

V Nersesyan - Nonlinearity, 2015 - iopscience.iop.org
In the Eulerian approach, the motion of an incompressible fluid is usually described by the
velocity field which is given by the Navier–Stokes system. The velocity field generates a flow …

Prescribing the motion of a set of particles in a three-dimensional perfect fluid
