Abstract
Small periodic disturbances are superposed to the equilibrium shape of the interface between cryolite and aluminum, and a linear analysis of their properties is proposed. Perturbations of electric quantities are first calculated, and then perturbations of velocities and pressure in the two liquids follow from 3D Navier-Stokes equations with a linear drag. The result is a characteristic equation which relates the parameters of the disturbance (wave length, rate of amplification) to the parameters of the cell (current densities, thicknesses of liquid layers, friction coefficients, equilibrium velocities…).
