Résumé : We construct a 19-bit lattice-gas model which is shown to exhibit spontaneous fluctuation correlations as produced in a thermal fluid system. Thus the lattice gas can be considered in the same sense as a real fluidas a reservoir of excitations with wavelengths and frequencies ranging from the microscopic level to the hydrodynamic scale. In particular the dynamic structure factor obtained from lattice-gas simulations is in agreement with the classical Rayleigh-Brillouin spectrum of real fluids. © 1992 The American Physical Society.
