| 摘 要： | 为了探索对转压气机流场特性，积累相关设计经验，本文进行在前后级转子等转速压比和效率特性试验基础上，着重进行了前后级转子不同转差下的特性实验。同时，借助CFD技术，辅助分析了转差对压气机特性及流场的影响。结果表明，转差变化引起压气机性能与流场结构发生显著变化，是影响压气机性能的主要因素之一。

| Abstract: | Preliminary researches on the rotating-speed difference in the counter-rotating compressor are presented. Some different rotating-speed differences were introduced and tested on a dual-stage axial counter-rotating compressor. A comparison of the results of a computational simulation and an experimental measurement indicates a good agreement between them. Consequently, it is verified that the rotating-speed difference is one of the important factors to effect on the performance characteristic and change the flow flied of the compressor. |
