| 摘 要： | 采用全三维粘性数值模拟手段，通过与按常规设计转子对比的方法，分析研究了大小叶片轴流压气机转子流动特性，分析结果表明，大小叶片转子流场在叶根亚声速区的流通能力增强，在叶尖跨声速区可以产生更加有利的激波体系，小叶片可以有效地控制叶栅槽道中气流扩散，在较高负荷和相同喘振裕度的条件下，大小叶片转子可以比按常规设计的转子在更高的压比，效率和流量下工作。

| Abstract: | The flow characteristics of one axial compressor rotor with splitter and two normally designed rotors with different solidities were analyzed by the 3 D viscous code The comparison shows that the mass flux in hub region was large and the shock wave system in tip region was desired The analysis results show that the flow diffusion was effectively controlled by splitter According to the calculated characteristics,the rotor with splitter can be operated with higher total pressure ratio, higher efficiency and larger mass flow than normally designed rotors, under the high loaded condition and with the same surge margin |
