摘要：

A lattice Boltzmann equation method for simulating multiphase immiscible fluid flows with variation of density and viscosity. based on the model proposed by Gunstensen et al. for two-component immiscible fluids [Phys. Rev A 43. 4320 (1991)] is developed. The numerical measurements of surface tension and viscosity agree well with theoretical predictions. Several basic numerical tests, including spinodal decomposition, two-phase fluid flows in two-dimensional channels, and two-phase viscous fingering, are shown in agreement of experiments and analytical solutions.
