摘要
燃气轮机是关系国家安全和国民经济发展的核心装备，排气扩压器气动性能对燃气轮机整机效率有重要影响。排气扩压器与上游流场的相互作用及其复杂的几何结构，导致了扩压器内流场易分离、多损失的流动特征。为探明扩压器的流动特征及其与透平的耦合机理，综述了国内外扩压器气动性能和优化设计的研究现状，讨论了扩压器设计与优化方面未来的研究方向，未来的研究需要充分考虑透平和扩压器的相互作用以及将参数化等方法引入扩压器优化设计问题以提高工作效率。
Abstract
Gas turbine is the important equipment used in security and economic field of the country. The aerodynamic performance of exhaust diffuser has an important influence on the thermodynamic efficiency of gas turbine. The flow interaction between the exhaust diffuser and the upstream turbine and the complex geometrical configurations leads to the strong vortex pattern and high flow losses in the diffuser which reduces the performance of the upstream turbine and exhaust diffuser. In order to investigate the flow characteristics of diffusers and the coupling mechanism between the diffuser and the turbine
the research status of aerodynamic performance and optimal design of diffusers at home and abroad was reviewed. The prospect of research on the design and optimization of the diffuser was discussed. The interaction between the turbine and the diffuser should be fully considered in future research. Parameterization and other methods were introduced into the optimal design of the diffuser to improve the working efficiency.
