Query: Lattice Boltzmann model with self-tuning equation of state for
  multiphase flows   A novel lattice Boltzmann (LB) model for multiphase flows is developed that
complies with the thermodynamic foundations of kinetic theory. By directly
devising the collision term for LB equation at the discrete level, a
self-tuning equation of state is achieved, which can be interpreted as the
incorporation of short-range molecular interaction. A pairwise interaction
force is introduced to mimic the long-range molecular interaction, which is
responsible for interfacial dynamics. The derived pressure tensor is naturally
consistent with thermodynamic theory, and surface tension and interface
thickness can be independently prescribed.
