中文摘要：

在这份报纸，一个基于 pseudopotential 的 multiple-relaxation-time 格子 Boltzmann 模型为 multicomponent/multiphase 流动系统被建议。不同于在文学的以前的模型，现在的模型不仅与不同分子的重量，不同粘性和不同 Schmidt 数字启用 multicomponent 流动的学习，而且保证没有调用另外的插值，每个部件的分发功能在一样的方形的格子上演变。而且， Chapman-Enskog 分析证明礼品在正确水动力学方程为结果建模，并且满足 indifferentiability 原则。数字确认锻练进一步证明礼品的有利表演当模特儿。

英文摘要：

In this paper, a pseudopotential-based multiplerelaxation-time lattice Boltzmann model is proposed for multicomponent/multiphase flow systems. Unlike previous models in the literature, the present model not only enables the study of multicomponent flows with different molecular weights, different viscosities and different Schmidt numbers, but also ensures that the distribution function of each component evolves on the same square lattice without invoking ad- ditional interpolations. Furthermore, the Chapman-Enskog analysis shows that the present model results in the correct hydrodynamic equations, and satisfies the indifferentiability principle. The numerical validation exercises further demonstrate that the favorable performance of the present model.
