Abstract
Consider a rigid body SâR3 immersed in an infinitely extended Navier-Stokes fluid. We are interested in self-propelled motions of S in the steady state regime of the system rigid body-fluid, assuming that the mechanism used by the body to reach such a motion is modeled through a distribution of velocities vâ on âS. If the velocity V of S is given, can we find vâ that generates V? We show that this can be solved as a control problem in which vâ is a six-dimensional control such that either SuppvââÎ, an arbitrary nonempty open subset of âΩ, or vââ n|âΩ=0. We also show that one of the self-propelled conditions implies a better summability of the fluid velocity.
