基于小波理论的平面叶栅优化设计

Optimal Design of Plane Cascades Based on Wavelet Theory

应用最优控制理论和Ｌａｇｒａｎｇｅ插值建立了任意回转面三元叶片的平面叶栅优化设计的数学模型。用小波理论求解此模型得到一批数值结果。结果分析表明小波方法较传统方法更加有效。

Based on the optimal control theory and Lagrange interpolation an optimal design model of plane cascades of 3D blade in an arbitrary surface of revolution is established. Using wavelet theory to solve the model, and lots of numerical results are obtained. The results show that the wavelet method is more effective than the conventional methods.
