摘　　要：本文给出了一种多段翼型绕流的分区贴体网格生成方法。采用泊松方程的解来给出贴体网格的坐标,泊松方程中的源项通过靠近边界的网格间距和正交性来决定,本文对分区网格的区域边界的选择作了讨论,采用生成的分区贴体网格计算了绕多段翼型位流的解,其结果与实验所得是很一致的。A method has been developed which generates the body-fitted coordinates of multi-element airfoils by using of a grid patching technique. The body-fitted coordinates are numerically generated by solving the elliptic grid generations of Thompson, and the source terms suggested by Thomas are used to control the space and orthogonality near the grid boundary. This paper also discusses how to choose the region interfaces. This patched grid is used to calculate the potential flow around multi-element airfoils and the results are in good agreement with the independent methods.
