摘　　要：采用多块结构网格和分区求解技术对多段翼型绕流进行雷诺平均NS方程数值模拟 ,并将计算的压力分布与实验进行了比较 .Grid generation and flow analysis methods for multi-element airfoil based on multi-block point-to-point patched grid technology are developed. Some strategies are developed to improve the efficiency, accuracy and applicability of the method.Several flow cases about multi-element airfoils are computed with the present method in order to validate it. Numerical results are in agreement with experiment data. Flow field visualization shows that the present method has good resolution in flow details.
