Abstract:

Lattice Boltzmann simulations are used to study the phase ordering of a system quenched into a lamellar phase. Hydrodynamic modes are found to be essential for the fluid to avoid frozen metastable configurations and reach the equilibrium state. We also show that a shear imposed on an equilibrium array of droplets can induce a micellar-lamellar transition. ©Société Itoliana di Fisica.

Abstract:

We outline the lattice Boltzmann approach to modeling complex fluids and discuss where it can provide additional information to more conventional macroscopic or microscopic simulations. The method is illustrated by considering contact line dynamics in a binary fluid. (C) 1999 Elsevier Science B.V. All rights reserved.

Abstract:

We use a lattice Boltzmann scheme within which the noise can be turned on and off to investigate the effect of stochastic terms on the phase ordering of a two-dimensional binary fluid. Sufficiently strong noise slows the growth in the hydrodynamic regime, changing the growth exponent [Formula Presented] to [Formula Presented]. © 1999 The American Physical Society.
