| 摘 要： | 本文以考虑非定常流动的完整性为线索,总结概述了先前气动设计体系的困难与限制,在此基础上,以描述叶轮机流动的时均和时间精确模型为核心分别从其构成和标志性技术对叶轮机时均和非定常气动设计体系进行了初步诠释。文章认为促成时均(准四维)和非定常(四维)气动设计体系现实应用是叶轮机发展的最后契机。

| Abstract: | According to the integrality of considering about flow unsteadiness, the difficulties and limitations of the previous aerodynamic design systems are summarized. On the basis of Time-Average and Time-Accurate flow models, the constitution and key techniques of the time-average and unsteady aerodynamic design system are described. It is remarked that the advancement towards the time-average and unsteady aerodynamic design will be the eventual opportunities to promote the turbomachinery technology. |
