| 摘 要： | 发展了一个叶轮机械叶片全三维粘性杂交问题的气动优化设计系统。该系统包括分析技术与组合优化技术的耦合：前者基于高精度、鲁棒型的数值分析方法，已成功地用于蒸汽透平叶片的流动分析．并经详细考核已将其纳入到了实际的叶片气动设计体系；后者基于优秀的iSIGHT商用优化平台．通过对多种优化方法的集成从而发展了组合的叶片全三维气动优化策略。数值结果与试验数据的比较表明了这一气动优化设计系统真正纳入到工业设计体系是完全可能的。

| Abstract: | An aerodynamic optimization system for the hybrid three-dimensional blade design, coupled with computational fluid dynamic analysis and integrated optimization algorithms, was developed in Tsinghua University. The higher-order accurate robust CFD method has been utilized for development of steam turbine blade flow analysis, its dependability has been validated by comparing the numerical results with model turbine test data. The hybrid three-dimensional optimization method based on iSIGHT commercial software has been developed for turbine blade design. The overall technical integration is starting to be used for further design optimizations and efficiency enhancement of steam turbines. |
