摘　　要：完善了应用Ｄｅｌａｎｎａｙ原理生成非结构网格的ＢｏｗｙｅｒＷａｔｓｏｎ方法。通过求解简化Ｐｏｉｓｓｉｏｎ方程，灵活地控制网格的疏密；通过网格层次的区分，提高了网格的贴体性能；并通过分区。A method based on Bowyer Watson algorithm is used for generation of unstructured grid. The density of grid is controlled by solving Poission Equations. The Strategy of grid improves the quality of body fitting. The viscous grid is accomplished by combining the O type in viscous zone and normal grid in other zones.
