Query: Static and dynamic properties of a particle-based algorithm for
  non-ideal fluids and binary mixtures   A recently introduced particle-based model for fluid dynamics with effective
excluded volume interactions is analyzed in detail. The interactions are
modeled by means of stochastic multiparticle collisions which are biased and
depend on local velocities and densities. Momentum and energy are exactly
conserved locally. The isotropy and relaxation to equilibrium are analyzed and
measured. It is shown how a discrete-time projection operator technique can be
used to obtain Green-Kubo relations for the transport coefficients. Because of
a large viscosity no long-time tails in the velocity auto-correlation and
stress correlation functions were seen. Strongly reduced self-diffusion due to
caging and an order/disorder transition is found at high collision frequency,
where clouds consisting of at least four particles form a cubic phase. These
structures were analyzed by measuring the pair-correlation function above and
below the transition. Finally, the algorithm is extended to binary mixtures
which phase-separate above a critical collision rate.
