摘要：

A Galilean invariant model of the lattice Boltzmann method (LBM) for multiphase fluid hows using free-energy approach is proposed. The asymptotic theory proposed by Sone (1971) is applied to the LBM model for multiphase fluid flows using the free-energy approach developed by Swift et al. [Phys. Rev. Lett. 75 (1995) 830] and governing equations for macroscopic variables of the model are obtained. From the governing equations the condition of a Galilean invariant LBM model is identified. In two problems, moving droplet and drop deformation and breakup in a shear how Galilean invariance of the proposed model is demonstrated. (C) 2000 Elsevier Science B.V. All rights reserved.
