A lattice Boltzmann model of ternary fluid mixtures

Abstract

A lattice Boltzmann model is introduced which simulates oil-water-surfactant\nmixtures. The model is based on a Ginzburg-Landau free energy with two scalar\norder parameters. Diffusive and hydrodynamic transport is included. Results are\npresented showing how the surfactant diffuses to the oil-water interfaces thus\nlowering the surface tension and leading to spontaneous emulsification. The\nrate of emulsification depends on the viscosity of the ternary fluid.\n
