针对用于燃气轮机的四端口通流波转子,首先将通道内部复杂的压力波系简化,建立解析的数学模型,并依据国外的实验结果验证其正确性,最终用该解析模型分析波转子的边界条件、波系结构、性能以及压气机、涡轮、燃烧室的相关参数之间的关系.结果表明:提高波转子的高压空气出口反压可以有效提高波转子压比,这是波转子内部波系整体性增强的结果;合理地设计压气机与涡轮可以优化波转子的性能;波转子与燃烧室的匹配会制约燃烧室的设计,而提高燃烧室的总压恢复系数则有利于波转子压缩效率的提高.
For the four-port through-flow rotor used in gas turbines, firstly, the complex pressure wave system in the passage is simplified, the analytical mathematical model is established, and the correctness is verified according to the foreign experimental results. Finally, the analytical model is used to analyze the boundary of the wave rotor The results show that increasing the backpressure of the high-pressure air outlet of the rotor can effectively increase the pressure ratio of the wave rotor, which is the result of the internal wave system of the wave rotor The result of the overall enhancement; rational design of the compressor and turbine can optimize the performance of the rotor; match the rotor and the combustion chamber will restrict the design of the combustion chamber, and improve the total pressure recovery coefficient of the combustion chamber is conducive to wave rotor compression efficiency Improve.
