摘　　要：用新近发展的格子玻耳兹曼方法对圆柱绕流现象进行了数值模拟计算,将模拟结果与实验结果进行了比较分析,获得了很好的一致性,反映出相同的流动特征。通过实际算例的应用,对格子玻耳兹曼方法的优点、发展潜力和目前存在的主要问题进行了讨论。A flow crossing a vertical column was simulated by the newly developed Lattice Boltzmann method. The simulation results were checked by the experiments which were made by other researchers. Good agreements and identical characteristics were obtained. On the bases of practical simulation, the advantages, developing potential and the main existing problems of Lattice Boltzmann method were discussed.
