Real-coded lattice gas model for ternary amphiphilic fluids

We have developed an amphiphilic surfactant model in the framework of the real-coded lattice gas (RLG), in order to analyze the dynamics and structure of ternary fluids. Formation of both the oil-in-water and the bicontinuous microemulsion phases, as well as the reduction of surface tension by adsorption of surfactant at interface are successfully reproduced in numerical simulations. Our model is simple in terms of description and implementation, however, complex structures and dynamic behavior of the ternary fluids emerge from the collective dynamics of the RLG and surfactant particles.
