A three-dimensional lattice-gas model for amphiphilic fluid dynamics

We describe a three-dimensional hydrodynamic lattice-gas model of amphiphil ic fluids. This model of the non-equilibrium properties of oil-water-surfac tant systems, which is a non-trivial extension of an earlier two-dimensiona l realization due to Boghosian, Coveney and Emerton, can be studied effecti vely only when it is implemented using high-performance computing and visua lization techniques. We describe essential aspects of the model's theoretic al basis and computer implementation, and report on the phenomenological pr operties of the model which confirm that it correctly captures binary oil-w ater and surfactant-water behaviour, as well as the complex phase behaviour of ternary amphiphilic fluids.
