| Résumé : | We analyze the role of the relaxation of double layers on the wave motion at a fluid-fluid interface undergoing an electrical constraint. For the transversal wave propagation the influence of the electrical terms contributes to an increase of the damping and of the propagation rate. The onset of the hydrodynamic surface instability is related either to negative electrical contributions of the surface tension or to the electrical quantities in the coupling between longitudinal and transversal motion. New criteria of convective instability related to mechanical and electrochemical properties of the bulk phases are derived. Experimental examples (propagation of transversal waves, emulsification, and surface convective motion) are discussed in the frame of the theory. © 1983. |
