Two-dimensional chaotic mixing of Newtonian fluids with active interfaces was investigated numerically to disclose influences on the formation of fine-scale structures in melts which may be captured by solidification to yield composites. Mixing of two immiscible fluids was confined to a rectangular cavity with periodically driven upper and lower surfaces. Interfacial forces and the interactions via the interface with the transient flow fields in each phase were considered. The evolving morphologies of active interfaces and interactions with flow fields in both the minor and major phases were disclosed for different interfacial tensions and phase viscosity ratios.
