  9. Lattice-Boltzman modeling.
    We used Lattice-Boltzmann modeling for the binary fluids to study:
    1. The dynamics of the binary fluids within the 2D patterned microchannel:
      We have introduced the patterned substrate by means of the appropriate surface potential, decaying away from the substrate.

    2. Phase separation of a binary fluid with the immobile nanoscale particle. The particles are taken to be wetted by the A (red) fluid.
      Morphology at late times for:
      Weak particle/fluid interactionStrong particle/fluid interaction
      We found, that:
      • For sufficiently strong interaction, domains are pinned to finite size at late times
      • Hydrodynamics promote the domain grows at early times
      • The chemical nature of the particles (effective strength and range of the wetting) essentially alters the dynamics of the phase separation as well as promotes the saturation of the domain size.

    In terms of the Lattice-Boltzmann modeling, we introduce the spatially non-uniform external potential (for the interaction with the substrate or with the particles) into the Lattice-Boltzmann method (free energy approach) for the binary fluids. Recently we have also developed a Lattice-Boltzmann scheme for ternary fluids with chemical reaction between the components.
