Mean-Field-Scaling in Lattice Boltzmann Fluid Mixtures



Nicos Martys, Jack F. Douglas


Basic equilibrium properties of Lattice Boltzmann (LB) fluid mixtures (coexistence curve, surface tension, and interfacial profile) are calculated to characterize the critical phenomena occurring in these model liquids and to establish a reduced variable description allowing a comparison with real fluid mixtures. We observe mean-field critical exponents and amplitudes so that the LB model may be useful for modeling high molecular weight polymer blends and other fluid mixtures that are usually approximated over a wide temperature range by mean-field theory.
