摘　　要：对格子Boltzmann方法的本质及Shan-Chen模型的核心机制进行了全面阐述,并从应用实例角度对基于Shan-Chen模型的格子Boltzmann方法在微流动模拟方面的有效性、适应性进行了详细分析.结果表明,Shan-Chen模型易于耦合微观条件下占主导作用的微观力,拓宽了格子Boltzmann方法在微流动模拟方面的应用.同时,Shan-Chen模型在润湿性边界条件表征方面的优势,使得这种方法在微结构表面的滑移效应模拟方面具有很好的应用前景.In a numerical simulation of microscale flow,it is difficult to reasonablly handle the interaction between microscopic particles and to improve computational efficiency.This paper discusses the Shan-Chentype lattice Boltzmann method and its implementation.The applications of the model in various microfluidic situations are reviewed,and the effectiveness of the model is analyzed.The simulations show that Shan-Chen-type lattice Boltzmann method is easy to be implemented with the micro force and has capability and efficiency in computational microfluidics,and its applications are prospected.At the same time,because of easiness in dealing with wettability boundary,Shan-Chen-type lattice Boltzmann method has experienced tremendous advances in microstructure simulation with slip effect.
