This thesis is devoted to the study of a deformable material interface between two immiscible moving<p>media, both of them being magnetizable. The first part concerns the establishment of a complete set of dynamical equations allowing a complete description of the non equilibrium phenomena including a coupling between the internal angular momentum and the electromagnetic field. The effects of the relaxation processes are also discussed. We show that the deformation of the interface introduces a nonlinear term, proportional to the mean curvature, in<p>the surface dynamical equations of mass momentum and angular momentum. That term<p>intervenes also in the singular magnetic and electric fields inside the interface which lead to<p>the influence of currents and charge densities at the interface. In a second part, we give the expression<p>for the entropy production inside the interface as well as in the bulk phase. Using the general principles of non equilibrium thermodynamics, we compute the different thermodynamical fluxes. / Doctorat en Sciences / info:eu-repo/semantics/nonPublished
