本文讨论了叶轮机械中三维叶片的优化方法,并利用二维正反问题程序和三维N-S正问题程序作为工具,将二维叶型的改型与三维叶片的周向弯曲两种优化设计技术相结合,对工程应用中一实际叶片进行了改型优化,数值分析表明,取得了较好的优化效果
The optimum design methods of three-dimensional bladeswere discussed in this paper. Using the codes of 2D direct and inverseproblems and 3D N-S direct problem, a practical blade inengineering was improved by combination of two optimum designtechniques that are revision of 2D blade profile and the circumferentialcurving of 3D blade. The better effect was achieved in numerical tests
