| Résumé : | The two-way coupling model for wave motion in a two-phase medium "fluid-elastic walls" accounting for interaction between those phases is considered within the frames of the boundary layer type approximation. An asymptotic linearized model including Navier-Stokes equations for the viscous incompressible fluid and the deformable plate motion equations for elastic walls is analyzed within a wide range of governing parameters variations. The dispersion relationship for different Reynolds numbers shows different oscillation regimes. The structure of the fluid flow is studied in detail for the two asymptotic limit cases of high and low Reynolds numbers. The results show that the intensity of fluid mass transfer induced in a fluid-filled channel with vibrating walls increases when increasing the vibrational Reynolds number. Contrary to the existing opinion, which considers the traveling wave regime of wall oscillations to be the basic mechanism generating the fluid flow, it is proved that the mean flux induced by standing waves could surpass the flux induced by the traveling waves in a range of one order of Reynolds number. © 2002 American Institute of Physics. |
