格子Boltzmann方法（Lattice Boltzmann Method, LBM）是近年来得到迅速发展并具有广阔应用前景的数值模拟方法。与基于连续介质假设的传统流体力学计算方法不同，LBM是从介观层次的流体粒子出发，基于动理学模型，假设这些流体粒子按规定的格线方向进行迁移碰撞相互作用，经过演化计算后得出符合物理规律的数值结果。与其它传统数值方法相比，LBM在复杂边界及几何条件、多相流模拟等方面具有明显的优势。并且LBM具有算法简单，容易编程实现的特点，非常适用于大规模并行计算。-Lattice Boltzmann Method (Lattice Boltzmann Method, LBM) has developed rapidly in recent years and has broad application prospects of numerical simulation methods. Unlike traditional CFD methods based on continuum hypothesis, LBM　mesoscopic fluid particle starting kinetic model, assuming that fluid particles according to a predetermined orientation of the grid migrate collision interaction, calculated after evolution the numerical results are in line with the laws of physics. Compared with other traditional numerical methods, LBM has obvious advantages in a complex geometry and boundary conditions, multiphase flow simulation and so on. LBM has a simple algorithm and easy programming features, ideal for massively parallel computing.
