采用离散型函数和B样条函数两种参数化方法生成叶片快照,研究比较基于单快照叶片和双快照叶片的Gappy POD拟合能力.引入流场求解,发展一种基于迭代偏差修正的Gappy POD反设计方法,并开展二维叶片表面压力分布的反设计研究.结果表明:双快照叶片方法能够有效提高Gappy POD的拟合空间和拟合精度,基于迭代偏差修正的反设计方法能够显著改善Gappy POD反设计方法的精度.“,”The parameterization methods of discrete shape function and B-spline function are employed to obtain the profile of blade snapshots.The description ability of Gappy POD by different snapshot approaches is evaluated and compared.An iterative inverse design method is introduced based on error correction to the target.Two inverse design studies of two-dimensional turbine blades are performed to achieve the given pressure distributions.The results demonstrate that the description ability of Gappy POD can be improved by the two-blades-based snapshot approach;significant improvements of the design results can be obtained by using the proposed iterative inverse design method.
