Using a Boltzmann approximation, we calculate the surface tension as a function of population density in a momentum-conserving lattice-gas model of immiscible fluids in two dimensions. The calculation, which predicts that the surface tension vanishes below a critical density, is compared to measurements made from simulations of flat interfaces and bubbles; the fit of theory to data is qualitatively good. Equilibrium fluctuations of flat interfaces are also studied. The fluctuations are empirically observed to be classical, decaying like the inverse square of wavenumber and obeying qualitatively the equipartition of surface energy.À partir de l'approximation de Boltzmann, nous calculons la tension superficielle en fonction de la den...
