Hydrodynamics of surface phenomena in the presence of a double layer

The paper is concerned with the development of models describing phase boundaries between two electrically conducting media in the presence of a double layer. An example of such an interface is the surface between a liquid metal (mercury, gallium, amalgams) and an electrolyte solution. The charge of the double layer affects the surface tension, which leads to a number of effects known as electrocapillary phenomena. The corresponding system of equations of motion is closed using methods of nonequilibrium thermodynamics.
