摘　　要：提出了一种基于插值的latticeBoltzmann方法的非均匀网格算法 ,给出了计算步骤 ;对典型的二维恒定方腔流、恒定和非恒定圆柱绕流问题进行了模拟分析 ,所得结果的正确性证明了该算法是有效。A nonuniform mech grid algorithm for the lattice Boltzmann method based on interpolation technique, with detailed calculation process, is presented. Classical two dimensional flows, including lid driven cavity flow, steady and unsteady flow around a circular cylinder, are simulated using the algorithm. Calculation results and flow patterns are in agreement with other numerical and experimental results. It is shown that the nonuniform mesh grid algorithm is feasible, efficient and practical.
