Resumen en inglés | By using density functional theory, we analyze an inhomogeneous fluid mixture composed of an arbitrary number of species within mean field approximation. Under the assumption that the interfacial region behaves as an elastic continuous medium, we calculate the stress tensor and the equilibrium grand potential of the system for different surfaces. It is found that, unlike the single component system, there exist multiple coexistence regions induced by the diversity of interaction potentials between the different species. Surface properties are calculated for a step-like density profile and consistency with the monocomponent system is verified for both the same formalism and other approaches at the level of surface tension |
