EFFICIENT SIMULATIONS OF MICROSCOPIC FLUIDS - ALGORITHM AND EXPERIMENTS

A strategy to make efficient simulations of systems of several thousan d particles interacting via a piecewise constant potential is describe d. A performance of several million collisions per hour is perfectly a ttainable in present day standard workstations. This program is partic ularly appropriate for hydrodynamic studies at a microscopic level in situations near or far from thermodynamic equilibrium. Two illustrativ e applications are summarily described: free thermal convection and Po iseuille flux.
