摘　　要：随着计算流体力学(CFD)的迅速发展,对作为CFD关键技术之一的网格生成技术提出了更高的要求.传统的网格生成方法一般耗费机时较多且复杂难用,或者生成的网格正交性较差.笔者在传统方法的基础上,提出了一种结合分块网格技术的多方向混合插值网格生成方法,其中插值系数对各块子区域网格的正交性具有可调节作用,能够处理各种复杂边界,生成的网格正交性好,适用范围较广,耗费机时也相对较少.大量的计算实例证明了新方法在网格正交性、适用性等方面都具有优势.Mesh generator is one of the key techniques of computational fluid dynamics (CFD), Traditional mesh generation methods are too complex and require a considerable amount of CPU time, and the generated grids are less orthogonal. A multi-directional hybrid interpolation method, combined with multi-block technique, was proposed on the basis of traditional methods. The interpolation coefficients serve the adjustable function of each sub-domain and can deal with various complex boundaries. The meshes generated by the new method are more orthogonal and save computation time significantly. The method has superiority in meshes orthogonalization and applicability.
