| 摘 要： | 以NASARotor35为研究对象，应用数值模拟手段深入分析了该转子在近失速工况的流动特征，针对其叶片吸力面附面层分离和上端壁处严重的二次流动，对比研究了叶表抽吸和上端壁抽吸对该转子流场结构以及气动性能的影响。计算结果表明：两种抽吸形式均使压气机的压比和效率有所提高。叶表抽吸可有效控制叶片通道激波，减小叶片吸力面的分离...

| Abstract: | A numerical simulation has performed to study the flow structure of the NASA Rotor35 in the near stall condition.For the boundary layer separation on blade suction surface and serious secondary flow near the end-wall,the effect of boundary layer suction(BLS) on the flow structure and performance of the supersonic compressor rotor have been investigated by two forms of suction:blade surface suction and the end-wall suction.The results show that:pressure ratio and efficiency of the compressor are all improved... |
