A three-dimensional lattice gas model for amphiphilic fluid dynamics

TL;DR

This paper introduces a three-dimensional lattice-gas model for simulating amphiphilic fluids, capturing complex phase behaviors of oil-water-surfactant systems using high-performance computing.

Contribution

It extends a previous two-dimensional model to three dimensions and details its theoretical foundation and implementation for studying non-equilibrium amphiphilic fluid dynamics.

Findings

Model accurately reproduces binary oil-water and surfactant-water behaviors

Captures complex phase behavior of ternary amphiphilic fluids

Effective for studying non-equilibrium properties with HPC techniques

Abstract

We describe a three-dimensional hydrodynamic lattice-gas model of amphiphilic fluids. This model of the non-equilibrium properties of oil-water-surfactant systems, which is a non-trivial extension of an earlier two-dimensional realisation due to Boghosian, Coveney and Emerton [Boghosian, Coveney, and Emerton 1996, Proc. Roy. Soc. A 452, 1221-1250], can be studied effectively only when it is implemented using high-performance computing and visualisation techniques. We describe essential aspects of the model's theoretical basis and computer implementation, and report on the phenomenological properties of the model which confirm that it correctly captures binary oil-water and surfactant-water behaviour, as well as the complex phase behaviour of ternary amphiphilic fluids.
