摘要
本文采用一种新型的气动优化方法来求解透平静叶的多参数优化问题。本方法包括叶片参数化造型方法、3D叶片与网格生成程序、N.S.数值模拟和响应面方法。采用参数化造型方法来重构初始叶片,并引入设计变量。然后,修改设计变量,并结合3D叶片与网格生成程序,获得一系列不同的叶片。通过N.S.计算,获得叶片优化所需的样本空间。最后,采用一定优化策略,获得满足设计要求的叶片及其设计参数值。
In the present paper a novel aerodynamic optimization methodology is used herein for solving multi - parameter optimization problem of turbine stator blades This method is based on the blade parameterization, 3D blade and grid generation, N. S. numerical simulation（ FLUENT solver）and response suface method.
By using the present parameterization method the original blade was rebuilt and expressed by design parameters. After changing the design parameters and using the 3D blade and grid generator we could obtain a set of different blades. A N. S. solver was applied to create a number of samples for the blaed optimization. Finally using optimization method the newly optimized blade and their design parameters which satisfy the given requirement were obtained.
