Abstract
The aim of this paper is to investigate the problem of the vibrations of large arrays of elastic rods immersed in a perfect incompressible f luid. The case of an infinite spatially periodic bundle is firstly con sidered leading to use the Bloch wave method in order to describe the resonance spectrum of the coupled system. When the bundle is contained in a bounded domain, the homogenization technique combined with the B loch wave method allows to obtain the eigenspectrum which is formed of two eigenfrequencies (of infinite multiplicity), and of a continuous spectrum.
