Three-dimensional hydrodynamic lattice-gas simulations of ternary amphiphilic fluids under shear flow.
We describe the implementation of shear flow in a three-dimensional lattice-gas model for amphiphilic fluids. We investigate the effect of shear on the morphology of the bicontinuous ternary microemulsion phase, and in particular its effect on the formation and stability of a lamellar phase. Metastable lamellar phases were observed for both 32(3) and 64(3) systems subjected to shear, and the stability of preformed lamellar phases under shear flow established for both 64(3) and 128(3) systems. The effect of micellization on interfacial behaviour in these phases is discussed in the context of the linear non-equilibrium thermodynamic theory of rate processes and nonlinear Becker-Döring aggregation theory.
