Few remarks on noise control in fluid-structure modelling

The goal of this paper is to point out few difficulties which occur in fluid-structure modelling. The main point is the bad convergence which appears in the boundary layer between the fluid and the flexible structure when one uses an eigenmode approximation or a finite element with a too coarse mesh. In a first part the mathematical aspects of the coupled model are discussed. Then a control problem which aims at reducing the noise in the coupled system, is considered
