摘　　要：介绍了格子气自动机模型的特点,建立了具有完全对称性的7-Bit正六边形格子气自动机模型。应用该模型通过对典型管排流和隔板流问题的计算模拟,其结果清晰的表示出流体在流场内的流动细节,证明了模型的正确性和有效性。The characteristics of lattice gas automata model are analyzed. A 7-Bit lattice gas automata model with regular hexagonal grid is introduced and adopted to simulate typical flow through the tube banks and clapboards, the course of flow trough porous media can be acquired and shown in detail. The correctness and validity of the model is verified.
