中文摘要：
以实际风力机翼型族的优化设计为研究对象，通过在iSIGHT软件上集成计算流体力学（CVD）软件Fluent、数值求解软件Matlab以及自编变形网格生成软件，建立了针对风力机专用翼型的优化设计平台；该平台使用反设计优化方法，可以通过改变初始翼型的几何形状，进行流体力学分析，求解气动性能敏感导数的迭代过程，得到符合特定性能要求的翼型；通过RAE2822和S825翼型性能为目标的优化过程验证了该平台的有效性和准确性。该平台可用于实际风力机翼型族的优化设计。
英文摘要：
A optimization platform was constructed for the shape design of wind turbine airfoil, the platform is based on iSIGHT software and combines a CFD software （Fluent）, numerical computing software （Matlab）, grid generation pro- gram. Based on inverse design method, the platform can generate an airfoil that produces a specified surface pressure dis- tribution. The design procedure is based on the full solution of N-S equations to include the viscous physics which charac- terizes low speed wind turbine flow. The platform was demonstrated with several examples at transonic and subsonic speeds. The iteration process of the design optimization converged quickly and the design airfoil has a excellent consisten- cy to the target airfoil, that makes the platform attractive for practical wind turbine airfoil design.
