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。
The 3-D inverse problem approach is stagnant and turbine design relies heavily on computer optimization based on CFD analysis. However, as the design requirements become more sophisticated, the more design parameters, the more significant the optimization calculation, and the more difficult the general optimization method can meet the engineering practice requirements. Thus, the companion method, which has almost nothing to do with the number of calculation variables and design variables, has drawn much attention from the aviation field once introduced. In the process of development, the key problems of successive breakthroughs are taken as the main line, the research and application of attendant method to outflow field are introduced from the field of flow, and then the exploration of inward flow field is reviewed. The research results of concomitant method at home and abroad are reviewed. Based on this, the application of deepening in the field of turbomachinery design is put forward, and the prospect of accompaniment of the method is prospected.
