| 摘 要： | Lattice Boltzmanm方法(简称LBM)是一种基于分子运动论和统计力学理论的流体计算方法。详细分析了LBM的基本理论,系统介绍了曲线固体边界处理的新方法。与Navier-Stokes方程相比较,LBM在算法及复杂边界处理等方面更具有优势。该方法在多相流、多组分流、热传导、颗粒悬浮、紊流及微小流束等问题的模拟中已得到广泛应用。

| Abstract: | Lattice Boltzmann Method(LBM for short) is a fluid flow computation approach based on molecule movement and statistical theory.The basic theory of LBM is analyzed in detail,the new methods for curved boundary treatment are introduced.Compared with Navier-Stokes equations,LBM appears to have more advantages in arithmetic and complex boundary treatment.This method has been widely applied in multi-phase flows,multi-component flows,thermal flows,particulate suspensions,turbulent flow and micro-flows. |
