伴随方法用于叶轮机优化设计的回顾与展望

3维反问题方法停滞不前，叶轮机设计越加倚重基于CFD分析的计算机优化。然而，随着设计要求越发精细、设计参数越多，优化计算量越显著增加，一般优化方法越难以满足工程设计实践要求。因而，计算量与设计变量数目近乎无关的伴随方法一经引入便受到航空领域深刻关注。以伴随方法发展过程中顺次突破的关键问题为主线，从流动领域引入伴随方法到外流领域的研究与应用，再到内流领域的探索尝试，回顾了国内外关于伴随方法的研究成果；在此基础上，面向深化在叶轮机设计领域的应用，对伴随方法进一步发展做出了展望。

Retrospect and Prospect for Adjoint Method Applying to Turbomachiney Optimization Design

As no breakthrough occurs in three-dimensional(3D) inverse problem,the 3D design of turbomachinery increasingly depends on computer-based optimizations.However,with the design requirements becoming more sophisticated,more design parameters used lead to a more remarkable increase in computation cost,and the general optimization methods become much more difficult in meeting the requirements of engineering design practice.Thus,the adjoint method attracted much more attention in aeronautic field because its com...
